"What does it mean,“Rededicating your life to Christ” is a popular concept in modern Christian culture. It’s a decision made by a Christian who has fallen away from the practices of Christianity to turn back to Christ and strive to follow Him more completely. The act of suddenly returning to Christ is spoken of indirectly in Galatians 6:1, where the churc...h is exhorted to restore sinful believers by gently confronting them. Rededication is popular among older children and young adults who grew up in the church. Christians who were saved at a young age may come to realize that their understanding of what it means to follow Jesus was incomplete. In a desire to consciously choose to adhere to a newfound, deeper understanding of the gospel, believers may “rededicate” themselves to Christ.
However, falling away and returning to God is not how the Christian walk is supposed to look. Romans 12:1–2 explains that spiritual maturity is a gradual, ongoing process. Jesus said that to follow Him we should take up our cross daily (Luke 9:23). And 1 Corinthians 9:24 and Hebrews 12:1 speak of the Christian life as a race, meant to be run every day. Many people rededicate after every sin. It’s easy to get caught in a cycle of rededicating, striving to follow Jesus closely, failing, and rededicating again. But habitual sin is not a problem solved by rededicating. It’s a deeper issue that can only be solved with a greater understanding of the grace and love of God.
Still, rededication is a useful tool. It’s a way to deliberately reject sin and renew a love for Christ. The disciples went through a rededication of sorts when they saw the risen Jesus. Their half-hearted devotion turned into a desire to pour out their lives for His service. In the same way, whether because of a conviction about a sinful lifestyle or a greater understanding of the gift of Christ, we can choose to abandon our shallow devotion to Christ and devote ourselves to Him more fully.
