God’s Discipline: Grace Changes The Heart

Christians often hesitate to accept the idea that God no longer disciplines believers. A primary reason is that they do not understand what will motivate godly living. Laws, penalties, clear instructions, and consequences give us a sense of security that we will not give in to our worst inclinations.

While we need laws and consequences in society to maintain order (Romans 13:1-7)—and even within families to train children—they cannot change the heart. Paul describes it this way:

Colossians 2:23 (NLT) These rules may seem wise because they require strong devotion, pious self-denial, and severe bodily discipline. But they provide no help in conquering a person’s evil desires.

A person may outwardly obey most of the time, but that does not mean they obey willingly. If given the opportunity, they may still give in to their sinful desires because the rules did not change their heart—only their outward behavior. Jesus rebuked the Pharisees for having an outward appearance of righteousness but inwardly were full of hypocrisy and wickedness (Matthew 23:27-28).

God’s grace is far more powerful because it affects the heart. While Christians are certainly not perfect, they are remarkably different from who they once were because they have experienced the transformative power of the gospel. Paul describes how the gospel had changed pagans, thieves, the sexually immoral, greedy, drunkards, abusers, and swindlers into godly saints by the Spirit of God saying, “And that is what some of you were. But you were washed, you were sanctified, you were justified, in the name of the Lord Jesus Christ and by the Spirit of our God” (1 Corinthians 6:11).

Believing the gospel accomplishes this transformation in three primary ways:

1. Christians are humbled and grateful for God’s forgiveness. They become enamored with God for His unbelievable gift and are motivated to love Him in return.
2. Accepting that they are right with God gives them confidence that He will take care of them when they are in need, which reduces the temptation to turn to sin for satisfaction.
3. Upon believing the gospel, the Holy Spirit enters a believer’s heart and, from that moment on, continually works to produce love, godly desires, and the power to obey Him.

All these effects—and many more—come from believing the gospel. It is more than intellectual knowledge; it is an experience that forever changes a person.

Gratefulness Produces Fruit

Genuine obedience comes from love, not fear. Luke 15:28-32 tells the story of the prodigal son’s older brother, who became upset when his father showed grace to his younger brother. Although the older brother outwardly obeyed his father, he felt like a slave inwardly and offered his service resentfully.

Luke 15:28-30 (NLT) “The older brother was angry and wouldn’t go in. His father came out and begged him, but he replied, ‘All these years I’ve slaved for you and never once refused to do a single thing you told me to. And in all that time you never gave me even one young goat for a feast with my friends. Yet when this son of yours comes back after squandering your money on prostitutes, you celebrate by killing the fattened calf!’

When we obey God only out of fear, we can become bitter and resentful about giving up the things we want. We also tend to become judgmental and ungracious when we see others receiving grace. I used to have a negative attitude toward God’s grace, thinking, Why should others receive grace even if they disobey God while I have to sacrifice my desires to obey Him, or else suffer His punishment?

If we obey God only out of fear, we miss out on the joy of sincerely pleasing Him. God wants us to love Him, others, and ourselves (Matthew 22:36-40). The only way to do that is by accepting His grace and love toward us (1 John 4:19; John 15:5). God loves a cheerful giver, not one who gives reluctantly or under compulsion (2 Corinthians 9:7). He does not want us to please Him because we have to or because we are supposed to, but because we want to.

Gratitude stems from Christ’s payment on the cross. Romans 8:1-4 tells us there is no condemnation for those who are in Christ Jesus. Jesus traded the blessings He deserved for the curse and condemnation we deserved (Galatians 3:10-14; 2 Corinthians 8:9). God did not go soft on sin or change His mind about it. Instead, Jesus was brutally tortured and killed to pay its penalty—and He did so cheerfully, without compulsion, because He loves us (Hebrews 12:2; John 3:16; 10:18). As a result, no matter what sins we have committed, when we trust in Jesus we receive eternal life and God’s favor (Romans 3:21-25; 4:7-8).

The injustice is scandalous. I—a sinner—walk away free, while the perfect Son of God suffers humiliation and dies a slave’s death, whipped beyond recognition and subjected to one of the worst punishments humanity has ever inflicted.

Gratefulness is the only fitting response to such an unimaginable and undeserved gift. When we comprehend what Christ did for us, the cost He paid, and what it signified, we fall in love with Him.

Luke 7:40-48 illustrates how the one who is forgiven of a greater debt will love more. In this passage, Jesus sat at dinner with a Pharisee when a certain immoral woman anointed His feet with expensive perfume and wept. The Pharisee was outraged, but Jesus told a story about two people who owed different debts to a moneylender. He concluded that the one who had the greater debt forgiven would love the lender more (Luke 7:41-43). Jesus then contrasted the Pharisee’s hostile treatment of Him with the love the woman showed, saying, “her sins—and they are many—have been forgiven, so she has shown me much love. But a person who is forgiven little shows only little love” (Luke 7:47).

God’s grace makes us zealous to do good deeds (Titus 2:11-14). It compels us to no longer live for ourselves but for the One who died for us (2 Corinthians 5:14-17). His forgiveness inspires virtue, self-control, godliness, kindness, and love (2 Peter 1:5-9). It inspired Paul to work harder than all the other apostles (1 Corinthians 15:10).

Grace humbles us, makes us grateful, and fills us with love for God. It changes our hearts from an attitude of wanting to disobey Him to one that willingly desires to follow Him.

Trusting God’s Provision Produces Fruit

When David killed Uriah in order to marry Bathsheba, God rebuked him not for wanting another wife, but for obtaining one in a sinful way. God wanted David to bring his desires directly to Him so that He could provide for them with good things.

2 Samuel 12:7-9 …This is what the LORD, the God of Israel, says: ‘I anointed you king over Israel, and I delivered you from the hand of Saul. I gave your master’s house to you and your master’s wives into your arms. I gave you the house of Israel and Judah, and if that was not enough, I would have given you even more. Why then have you despised the command of the LORD by doing evil in His sight?

God was not ashamed that David wanted another wife; He was ashamed that David would trust in himself to obtain what he wanted through sin rather than trusting God’s righteous provision. James gives a similar lesson:

James 4:1-3 What causes conflicts and quarrels among you? Don’t they come from the passions at war within you? You crave what you do not have; you kill and covet, but are unable to obtain it. You quarrel and fight. You do not have, because you do not ask.

The point of these teachings is that those who trust in the Lord to provide are less tempted to sin. Instead of feeling desperate that their needs or desires will go unmet, they turn to the Lord for help, and He satisfies them with good things (Psalm 37:3-5; 103:5; 107:9; Jeremiah 2:13; Proverbs 3:5-6; 1 Peter 5:7; Matthew 6:31-33).

Psalm 34:8-10 Taste and see that the LORD is good; blessed is the man who takes refuge in Him! Fear the LORD, you His saints, for those who fear Him lack nothing. Young lions go lacking and hungry, but those who seek the LORD lack no good thing.

Grace gives us the confidence to turn to the Lord with our needs and desires, knowing that He will not reject or condemn us. It teaches us that Christ has put us in a position of favor with God so that we can expect good things from Him and not harm. This trust enables us to turn to Him when temptation arises and find satisfaction in His provision.

Hebrews 4:16 Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.

The Spirit Produces Fruit

The greatest influence on obedience in a believer’s life is not personal effort or willpower, but the activity of the Holy Spirit. When a person believes the gospel, the Holy Spirit enters their heart and begins changing them from the inside out.¹ This does not happen through fear, pressure, or guilt, but through patient love, grace, and confidence in God’s forgiveness.

In the New Covenant, God declares that He will write His laws on the believer’s heart. Rather than placing the responsibility on the believer to change their own heart, God assures victory by doing it Himself. And because this is a work of God and not human effort, it does not require scary threats. Instead, God produces this heart change while fully forgiving and forgetting our sins.

Hebrews 10:15-17 The Holy Spirit also testifies to us about this. First He says: “This is the covenant I will make with them after those days, declares the Lord. I will put My laws in their hearts and inscribe them on their minds.” Then He adds: “Their sins and lawless acts I will remember no more.”

God accomplishes this heart change through the power of the Spirit.

Ezekiel 36:27 And I will put My Spirit within you and cause you to walk in My statutes and to carefully observe My ordinances.

Romans 2:29 (NLT) And true circumcision is not merely obeying the letter of the law; rather, it is a change of heart produced by the Spirit. 

Philippians 3:3 (NLT) For we who worship by the Spirit of God are the ones who are truly circumcised. We rely on what Christ Jesus has done for us. We put no confidence in human effort

Philippians 1:11 (NLT) May you always be filled with the fruit of your salvation—the righteous character produced in your life by Jesus Christ—for this will bring much glory and praise to God.

Philippians 2:13 For it is God who works in you to will and to act on behalf of His good purpose.

Galatians 5:22-23 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

The Spirit does not threaten the believer into obedience. Rather, He helps them grow in understanding and embracing the gospel more fully.

Galatians 3:2-5 (NLT) Let me ask you this one question: Did you receive the Holy Spirit by obeying the law of Moses? Of course not! You received the Spirit because you believed the message you heard about Christ. How foolish can you be? After starting your new lives in the Spirit, why are you now trying to become perfect by your own human effort? Have you experienced so much for nothing? Surely it was not in vain, was it?

I ask you again, does God give you the Holy Spirit and work miracles among you because you obey the law? Of course not! It is because you believe the message you heard about Christ.

Jesus says it this way:

John 15:5 I am the vine and you are the branches. The one who remains in Me, and I in him, will bear much fruit. For apart from Me you can do nothing.

God Himself transforms the believer from the inside out. In this environment, fear, threats of discipline, and condemnation are no longer needed to bring about change. The process becomes far more peaceful, restful, and trusting.

The power to be a fruitful Christian comes from fully embracing the gospel—not from fearing discipline.

1 John 4:18 There is no fear in love, but perfect love drives out fear, because fear involves punishment. The one who fears has not been perfected in love.

Christians should not fear a gospel that teaches God no longer disciplines us for our sins. Instead, they should fully embrace the gospel message and experience the peaceful transformation it offers.
