Falling away then returning to God is a noble step and God honors the man or women that return to the Christian. Romans 12:1-2 explains that spiritual maturity is a gradual, ongoing process. Jesus said that to follow Him we should take 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. 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
