Every Christian tradition begins with a humbling truth found throughout the Bible: all of us have sinned and fallen short of God’s glory (Romans 3:23). God alone is perfect and the just Judge of all things (Deuteronomy 32:4; Psalm 9:7–8). He cannot treat sin as trivial, dismiss it, or remain in fellowship with it without being unjust (2 Samuel 12:13–15). Our sins separate us from Him (Psalm 5:4). He alone possesses immortality and is the author and sustainer of life (Acts 17:25). Without Him, we cannot live forever (1 Timothy 6:16). As Paul writes, “the wages of sin is death” (Romans 6:23).
Left to ourselves, we are under condemnation and cut off from the eternal life for which we were made (John 3:36). We cannot earn that life through good works, religious efforts, or moral improvement (Galatians 3:10). The standard is absolute perfection, and our best attempts fall short (James 2:10).
Into this desperate situation, God acted in love. Because He is just, He cannot overlook sin; yet because He is merciful, He refuses to leave humanity without hope. Scripture tells us that God demonstrated His own love toward us in this: while we were still sinners, Christ died for us (Romans 5:8). Or, in the familiar words of Jesus: “For God so loved the world, that he gave his only born Son, that whoever believes in him should not perish, but have eternal life” (John 3:16).
Here is the heart of the common Christian confession: the Lord Jesus Christ, the eternal Son of God, became fully human, lived a sinless life, died on the cross, and rose again on the third day. He received the punishment for our sins in His own body on the cross. His once-for-all sacrifice removed guilt and provides righteousness to all.
The resurrection confirms and completes the work. Jesus was delivered over to death for our sins and was raised to life for our justification. By raising Him from the dead, God publicly showed that the sacrifice was accepted.
The cross and the empty tomb together accomplish what no human effort ever could—the removal of condemnation, full forgiveness of sins, and the free gift of eternal life for those who are united to Christ by faith. What we could never earn or keep by our own strength, God has freely given in His Son.1
Everyone Is Invited
Christ’s sacrifice did not benefit only a select few. Scripture clearly teaches that He died for the sins of the whole world, and that the free gift of forgiveness and eternal life is sincerely offered to every person without distinction (1 John 2:2; Revelation 22:17).
1 Timothy 2:3-6 For this is good and acceptable in the sight of God our Savior, who desires all people to be saved and come to full knowledge of the truth. For there is one God and one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all, the testimony at the proper time
The only thing we can do to receive this gift is to admit we have sinned, trust solely in what the Lord Jesus Christ has done to provide eternal life, and openly declare our faith in Him.2 When God forgives us, He does so regardless of what sins we may have committed (Romans 3:27–28). We cannot take credit for our salvation; it is a free gift, not a reward for good works, so that none of us can boast (Ephesians 2:8–9). He saved us, washed away our sins, and gave us new birth and new life through the Holy Spirit—not because of any righteous things we have done, but because of His mercy (Titus 3:5).
Repentance
Admitting our guilt and turning to God for forgiveness is what Scripture calls repentance. At its heart, repentance is a change of mind. It is the recognition that we are not righteous on our own, that we cannot fix ourselves, and that we need God’s forgiveness and transforming power. It moves our trust away from ourselves and places it fully in God. This is something every true believer does when they first receive the gospel.3
Grace Changes Lives
A believer isn’t saved by their efforts to be a better person, nor is their salvation lost if they sin (1 John 2:1-2). Good works do, however, give evidence that faith is real (James 2:17–18).
This gospel produces deep gratitude in those humbled by its message. It compels believers to no longer live for themselves but for the One who died for them (2 Corinthians 5:14-15). God’s forgiveness inspires virtue, self-control, godliness, kindness, and love (2 Peter 1:5-8) and makes believers zealous to do good deeds (Titus 2:11-14), just as it inspired Paul to work harder than all the other apostles (1 Corinthians 15:10).
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. 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 [BSB]).
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 [BSB]).
This same grateful love marks the lives of sincere believers. They love God because He first loved them, and they love others because of the grace they have received (Colossians 1:6; 1 John 4:19).
Faith that Endures
Faith that understands and receives the gospel proves itself genuine by enduring to the end of the believer’s life. If someone later completely abandons the faith without returning, it reveals that their profession was never genuine to begin with (1 John 2:19).
However, even genuine faith can be tested by the world we live in. Deception, persecution, and temptations challenge believers’ faithfulness to the gospel. Left to themselves, believers could easily become discouraged and hopeless.
God does not leave believers to face these challenges alone. When a person turns to Him in sincere faith, God gives them a new heart and spirit made in perfect righteousness and places His own Spirit in their heart to remain with them forever.4 This is the moment a believer is born again to a life that cannot be destroyed.5 Although their earthly bodies will die because of sin, believers will receive a new body in heaven that is not tempted with sin.
The Spirit teaches, guides, and guards believers from deception.6 He strengthens, comforts, and protects them in persecution so they are not tested beyond what they can bear.7 Most significantly, He transforms them to be loyal and obedient to God so that their genuine faith endures to the end.8 The Holy Spirit guarantees that their once-genuine faith will never fail (Ephesians 1:13–14; 4:30).
Can God Preserve Believers?
The doctrine of Conditional Security teaches that while God assists in preserving the faith of believers, He does not take away free will and therefore cannot guarantee success. Warnings and examples against complete rejection of the gospel are applied to born-again believers, creating uncertainty about God’s promise to preserve His people.
However, such a view assumes uncertainty about God’s ability to preserve His people that does not exist in the text itself. The doctrine of Eternal Security argues that the warnings about ultimate falling away apply to nominal believers in whom the gospel never took root and who never received the Spirit. These individuals were only outwardly associated with the church.
As you continue through the chapters ahead, may God strengthen you in His grace and quiet any lingering doubts these debated passages may raise.
