Repentance involves submission. We have to recognize that, if we choose to surrender our lives to Christ, there is a sense in which choices have been made for us. 

“Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies.” (1 Corinthians 6:19-20)
