Revelations in Grace

A personal revelation of the gift of righteousness and grace through Christ Jesus.

Why does God Require Faith?

Most of us, including myself, would categorize ourselves as having weak faith. We want to believe in God, but we worry we might not have the faith needed to experience the miracle. This can be frustrating, especially when we read passages like these:

Mark 11:23-24 (NIV): “Truly I tell you, if anyone says to this mountain, ‘Go, throw yourself into the sea,’ and does not doubt in their heart but believes that what they say will happen, it will be done for them. Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours.”

James 1:5-7 (NIV): “If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. That person should not expect to receive anything from the Lord.”

The Necessity of Faith

The Bible is filled with examples where people missed out on the blessings God intended for them due to a lack of faith.

  1. The Israelites Failing to Enter the Promised Land: The Israelites were promised the land (Genesis 15), yet many failed to enter because they refused to believe God could overcome the giants there (Numbers 13-14). God had not sworn that every Israelite would enter, so He fulfilled His oath by granting it only to those who believed (Joshua 21:43-45).
  2. The Disciples Unable to Cast Out a Demon from a Boy: Jesus intended to heal the people of Israel and instructed His disciples to heal the sick and drive out demons (Matthew 10:1-15). The disciples had seen Jesus perform miracles and had even done so themselves, yet they couldn’t heal one demon-possessed boy. Jesus explained that their failure stemmed from a lack of faith, not a change in God’s will (Matthew 17:14-21).
  3. Jesus Unable to Perform Many Miracles in His Hometown: In Nazareth, Jesus aimed to perform miracles and teach as part of God’s plan, but the people’s familiarity with Him bred unbelief and offense. Due to their lack of faith, He did few mighty works there, limiting the blessings they received (Matthew 13:53-58; Mark 6:1-6).
  4. Peter Sinking While Walking on Water: Jesus demonstrated God’s power by walking on the sea and invited Peter to join Him. Peter began to sink when doubt crept in amid the wind and waves. His lack of faith prevented him from fully experiencing the miracle, though Jesus rescued him and encouraged his faith (Matthew 14:22-33).
  5. The Royal Officer Doubting God’s Promise of Provision During a Siege: During a famine in besieged Samaria, God promised through the prophet Elisha that abundant food would arrive the next day at low prices. The king’s officer mocked this as impossible and lacked faith. He lived to see the promise fulfilled but was trampled to death at the city gate and did not partake in it (2 Kings 7:1-2, 16-20).

When our prayers go unanswered, we want to comfort ourselves in our disappointment. Instead of admitting our weak faith, we may lose faith in God altogether, assuming the things we hoped for are not His will for us. This is dangerous, particularly when we deny the promises God presents to us in Scripture, rather than realizing we simply need more faith to experience them.

The Necessity of Patience

Often, God’s answers come later than expected, after we have given up hoping for them. When they arrive, we may not notice they are the very answers we prayed for. We may continue to assume that God doesn’t answer our prayers, when in fact He has—just not when we expected it. Abraham had faith that God would give him a son; he even performed the first recorded healing in the Bible, restoring Abimelech and his wives and servants from their inability to conceive—the same miracle he was awaiting from God for Sarah (Genesis 20:17-18). Yet, Sarah did not give birth until many more years had passed. Faith guarantees the answer, but we must wait patiently and expectantly to receive it in God’s timing, as Hebrews explains:

Hebrews 6:11-15 (NIV): We want each of you to show this same diligence to the very end, so that what you hope for may be fully realized. 12 We do not want you to become lazy, but to imitate those who through faith and patience inherit what has been promised.

13 When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself, 14 saying, “I will surely bless you and give you many descendants.” 15 And so after waiting patiently, Abraham received what was promised.

Faith and patience together make God’s promises a reality in our lives. Without them, we fail to fully experience or recognize the blessings He has promised. God swore to bless us in every way through Christ (Genesis 22:18; Galatians 3:8), demonstrating His compassion and deep desire to bless us. Moreover, God can accomplish His will even when no one believes in Him (Isaiah 45:4-6; 46:10; Daniel 4:35; Exodus 12:12; Proverbs 21:1; Romans 3:3-4; 9:17-18; Acts 2:23). So why does God expect faith before answering our prayers? Why doesn’t He perform miracles without it?

Why God Requires Faith

Doubt is not as innocent as it seems. It means we place our trust in something other than God—whether our own strength, wisdom, wealth, the experts, false gods, luck, magic, etc…. No one lives in complete hopelessness, so doubting God simply shifts our hope and confidence elsewhere. As Scripture warns:

Jeremiah 17:5-8 (NIV): “This is what the Lord says: ‘Cursed is the one who trusts in man, who draws strength from mere flesh and whose heart turns away from the Lord. That person will be like a bush in the wastelands; they will not see prosperity when it comes. They will dwell in the parched places of the desert, in a salt land where no one lives.

But blessed is the one who trusts in the Lord, whose confidence is in him. They will be like a tree planted by the water that sends out its roots by the stream. It does not fear when heat comes; its leaves are always green. It has no worries in a year of drought and never fails to bear fruit.’”

God does not answer prayers directed toward other gods—indeed, He should not (1 Kings 18:26-29; Judges 10:14; Isaiah 45:20; Jeremiah 2:27-28; Psalm 115:4-7; 1 Samuel 12:21; Isaiah 42:8; Isaiah 48:11; Exodus 20:3-5). If one prays to a false god and the true God answers the prayer out of compassion, the success is attributed to the idol. This gives one a false sense of security in the idol’s power and undermines our trust in the One who actually has the power to answer our prayers. In fact, such a person may go on to encourage others to worship the idol, including any man-made or disturbing practices its religion demands. It empowers God’s enemies and erodes trust in the gospel that alone saves us.

When we rely on worldly idols like our strength, wealth, skills, goodness, fortune, or cleverness—yet also pray to God—any miracles we experience may be misunderstood as an accomplishment of our own strength or wisdom. Suppose we pray for healing but base it on our own law-keeping or merit rather than Jesus’ blood. God shouldn’t heal under those conditions, as it would reinforce trust in self-righteousness. As Paul explains:

Galatians 3:3-6 (NIV): “Are you so foolish? After beginning by means of the Spirit, are you now trying to finish by means of the flesh? Have you experienced so much in vain—if it really was in vain? So again I ask, does God give you his Spirit and work miracles among you by the works of the law, or by your believing what you heard? So also Abraham ‘believed God, and it was credited to him as righteousness.’”

If God performs a miracle that validates self-righteousness, it falsely suggests we can earn miracles despite our sins—and by extension, eternal life—through our efforts. This strengthens misplaced confidence and undermines the humble realization that we are all sinners and only Jesus can be trusted to make us right with God.

That is why God wisely withholds answers to prayers rooted in idols or self-reliance—it preserves our faith in the gospel and prevents growth in false trusts. Riches, for example, are a blessing from God that He delights in giving to us (Genesis 24:35; Deuteronomy 8:17-18; 30:9), but if we misplace our trust in them, they instead become a curse (Proverbs 11:28; 30:7-9; Psalm 52:7; Ecclesiastes 5:10; Matthew 19:24; 1 Timothy 6:17).

How God Grows Faith

God is compassionate and deeply desires to bless, heal, and answer our prayers. If our confidence lies in our own strength, wisdom, fortune, skills, money, or other idols, how does He build faith strong enough to receive His blessings? Growing faith is a two-step process: dismantling confidence in ourselves or idols, and redirecting that trust solely to God. As Scripture states:

James 4:6 (NIV): “…God opposes the proud but shows favor to the humble.”

God opposes our pride in unreliable things for our good. Until we lose confidence in our false “gods,” we may not turn exclusively to the true God. This process can feel uncomfortable—we may sense our prayers going unheard, our trusted sources failing, and hopelessness growing (Galatians 3:10; 5:4). But as we recognize our misplaced trust and redirect it to the Lord, things improve (Galatians 3:13-14).

Jesus exemplified this in His ministry. He assured sinners with no self-confidence that their sins were forgiven, while exposing the sins of the self-righteous who trusted in their law-keeping. His goal was to undermine their false confidence, hoping they would turn to Him as the only reliable source of righteousness (Luke 18:9-14; 18:18-30; 19:1-9). In fact, this is the entire reason God gave the Mosaic Law to Israel as an example to the world: to dismantle our confidence in ourselves and to redirect our trust to Himself (Isaiah 45:22-25; Deuteronomy 31-32; Romans 3:20; Galatians 3:21-22).

How Can I Have Faith?

Having weak faith does not mean God will not answer your prayers. My life—and perhaps yours as well—is a testimony that God answers prayers even when we doubt Him.

When we turn to God for help, admitting our doubts, but with willingness to grow our faith in Him, He cultivates our faith into something more robust that can sustain the challenges of life and give us peace during its storms. He doesn’t altogether let us fail, being merciful to our doubts. God doesn’t actually need our faith to perform miracles—He was able to create the world even when no one believed in Him (Genesis 1) and give Zechariah a son when he doubted God (Luke 1:5-20). Rather, He grows our faith for our benefit.

When our doubts are challenged and overcome, we become steadfast in patience, even when facing great odds (James 1:3-4; Romans 5:3-5). It gives us assurance and peace that God can overcome the challenges we face (Hebrews 11:1; Philippians 4:6-7). We are not troubled by threats or worried by danger because we can remember times when we doubted God and yet He came to the rescue (Matthew 6:25-34; Psalm 34:19). It enables us to comfort those we love who worry or fear that God cannot save them or help in their time of need (2 Corinthians 1:3-4). It causes us to rest and wait on God in peace and confidence while the rest of the world frantically worries, plans, overthinks, and strives (Isaiah 30:15; Psalm 37:7). It teaches us that God is powerful when we are weak (1 Samuel 17:47; 2 Corinthians 12:9; Zechariah 4:6).

Take the story of King David as an example. We admire his courage to face Goliath alone, but we don’t realize that God had been training David for years prior to trust Him. David faced Goliath with courage because God had proven that He could defeat the lion and bear that had tried to attack David’s sheep in the past (1 Samuel 17:34-37).

God’s mercy never goes away (Lamentations 3:22-23), and He never makes us regret trusting in Him (Isaiah 49:23). Instead, He gives us enough success to motivate us to continue growing our confidence in Him and provides protection for when our faith fails (Psalm 34:22).

This is seen in the story of Peter walking on water (Matthew 14:28-31). Peter began to walk because his confidence was in the Lord, but his ability to walk on water was not the ultimate goal. Jesus wanted Peter to know that confidence in God makes even the impossible possible. Peter sank because he didn’t fully grasp that lesson—the waves and winds seemed greater than he expected. Jesus took hold of Peter’s hand, showing that God protects us from the dangers our unbelief can cause. The goal of the venture was not simply gaining the new ability to walk on water, but providing a gracious illustration that God is merciful toward our doubts and desires our confidence in Him to grow stronger. God could have prevented Peter from sinking despite his doubts, but He was looking out for Peter’s best interest—not only in that moment but also for his future, when he would be a leader in the faith for the early church. God can perform any miracle with any amount of faith, but His wisdom and love compel Him to exercise discretion for the individual’s present and future well-being and purpose. The lesson that waves and winds are not too strong for God allowed Peter to experience God’s peace when future decades brought winds and waves of uncertainty.

The father whose boy wasn’t healed is another example of this (Mark 9:14-29; Matthew 17:14-20). He initially took his boy to the disciples hoping that they could heal him. But because of the boy’s severe condition, the disciples didn’t have much confidence God was able to heal him. This brought them to Jesus, who nurtured their faith and reminded them that nothing is too hard for God (Jeremiah 32:17). The analogy Jesus gave about a mustard seed being enough faith to move mountains was meant to illustrate that God has unlimited patience toward our doubts and so can perform miracles even in the absence of faith, but His rebuke to the disciples for having weak faith shows that God wanted to use this healing to teach them that confidence in God alone assures victory. It may be that the disciples did not rely on prayer alone but tried herbal therapies or religious rituals common in Jesus’ day among the Jews to cast out demons, since Mark accounts that Jesus said, “This kind can only come out by prayer” (Mark 9:29), leaving us to wonder if the disciples actually even prayed. Later on, the disciples did even greater works than Jesus (John 14:12), showing that Jesus’ lesson did not discourage their faith but rather motivated it.

The Bible lists many other examples where God answered prayers of people who doubted Him, reminding us that placing any hope in the Lord, no matter how small, is rewarded (Matthew 14:28-31; John 20:24-29; Mark 4:35-41; Judges 6:36-40, 7; 1 Kings 19:1-18; Exodus 3:1-4:17; Genesis 18:10-15, 21:1-7; 2 Kings 20:1-11; Luke 18:9-14; John 11:1-44; Acts 12:1-17; 1 Samuel 1:9-20; Judges 4; Luke 1:5-20).

Understanding “Doubt” in James

When we express our desire to trust the Lord more and to leave other trusted idols behind, miracles bolster our faith because all the credit goes to Him, transforming small faith into great faith. That’s why God is merciful toward our doubts and performs miracles for those with weak but willing faith. As long as the miracle can grow our trust in Him, He forgives our wavering and acts.

Does James 1:6 seem to contradict this by demanding unwavering belief? Not when we examine the original Greek, which reveals key nuances in the word “doubt.” The passages in Mark 11:23-24 and James 1:5-7 (quoted at the article’s start) use “diakrinó,” implying wavering between options or divided allegiance—like being “double-minded” (James 1:8). In contrast, the father of the demon-possessed boy expressed “apistia,” a straightforward lack of faith without split loyalties.

This is why the New Living Translation clarifies James’s intent:

James 1:6 (NLT): But when you ask him, be sure that your faith is in God alone. Do not waver, for a person with divided loyalty is as unsettled as a wave of the sea that is blown and tossed by the wind.

Here, “doubt” refers to split allegiance, not mere uncertainty. We must pray ready to credit God alone for any answer, avoiding shared reliance on self, experts, or idols that could lead to misattribution. This harmonizes with the examples above, showing God’s grace for honest, undivided struggles.

Conclusion

In summary, most believers struggle with weak faith, yet it brings us comfort, peace, assurance, and confidence in difficult situations, allowing us to see and enjoy the miracles God delivers. As many biblical examples show, God requires faith because doubt shifts trust to unreliable idols or self, undermining the gospel and glorifying false sources. He grows our faith by compassionately dismantling misplaced confidences and redirecting them solely to Himself, often through challenging processes that lead to deeper reliance. Even the smallest willing faith is honored and strengthened through His responses, as illustrated by numerous biblical figures. Ultimately, by admitting our weakness and placing undivided hope in Him, we open the door to transformed lives filled with His promises.
