The first step to recommitting your life to God is to confess your sins to Him.
In 1 John 1:9 (Living bible) we read:
But if we confess our sins to him, he can be depended on to forgive us and to cleanse us from every wrong. And it is perfectly proper for God to do this for us because Christ died to wash away our sins.
How can we truly recommit our lives to God if we hold onto some parts of our lives? To fully give our lives to Him we must acknowledge everything we have done which was wrong, admit those wrongs, those sins, to God and repent, as only He can take those sins and wash them away, and forgive us…all because Jesus died to save us.
