We are all born sinners because humanity inherits a sinful nature from Adam and Eve, whose disobedience brought sin into the world. This sinful nature affects us from birth, influencing our thoughts, actions, and bodies, as evidenced in scripture (Psalm 51:5, Romans 5:12). We are unable to overcome our sin on our own, as even good actions cannot atone for sin or change our inherent nature (Ephesians 2:1-3). However, through Jesus Christ, fully God and fully man, who lived a perfect, sinless life and sacrificed Himself for our sins, we can receive forgiveness and be freed from the bondage of sin (Romans 5:17). Those who trust in Jesus will be empowered by the Holy Spirit, transformed into Christ's image, and one day be fully restored in heaven, free from sin forever (2 Corinthians 5:17, Revelation 21-22).
Although we are all born sinners, Jesus Christ has overcome sin. Jesus was fully human and fully God. As such, He was a perfect man, living a perfect life, without sinning. By sacrificing His life on the cross, He atoned for both our sinful nature and actions. All who put their trust in His death and resurrection can be forgiven and freed from bondage to sin. Just as Adam's sin spread sin throughout the world, Jesus' sacrifice defeated all sin (Romans 5:17).
In this life, we will always have a sinful nature. However, there are at least three promises for those who commit their lives to Jesus: First, their sin is not counted against them; in Christ we are completely forgiven (1 Corinthians 6:11; 2 Corinthians 5:21). Second, they will be empowered by the Holy Spirit to withstand the temptation to sin, and Jesus will work to transform their hearts so that they will become more like Him in nature (1 Corinthians 10:13, 2 Corinthians 5:17; Philippians 1:6; 2:12-13). Finally, one day they will be reunited with God in heaven and will be forever free of sin (Revelation 21—22). In Jesus, we need no longer be separated from God. We are not bound to our birth as sinners but can become children of God: "But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God" (John 1:12-13).
