For much of my life, whenever I heard a preacher preach about "repentance", I always thought of it as something like, a person had to be totally broken, kneeling "humbly" before God, and saying something like, "Oh God, I'm a horrible sinner. I'm not worthy to come to you, but I cry out to you. Change me...." The sinner had to admit his sin and recognize and admit the horribleness of it. (I'm being a little overly dramatic here, but, hopefully, you get the point.) But Jesus and the Bible didn't have that attitude.
(To the woman who as caught in adultery, after her accusers had left,) Jesus said, “Where are your accusers? Didn’t even one of them condemn you?”
11 “No, Lord,” she said.
And Jesus said, “Neither do I. Go and sin no more.” (John 8:10-11)
Jesus did not condemn her. He cared about her and wante what was best for her.
"Therefore, there is now no condemnation for those who are in Christ Jesus, 2 because through Christ Jesus the law of the Spirit who gives life has set you[a] free from the law of sin and death." Romans 8:1-2
In recent years my view of repentance has change markedly. I see repentance as more of a realization, "Oh, I've been doing that incorrectly." and with that a decision to do things differently.
Repentance is not a one time event, but rather it is a continually change in the way one thinks. It's a matter of being open to correction, of being willing to change and improve the way one thinks and acts.
