The right answer is contrition, and “go and sin no more”
Recognize the sin, without condemning the sinner.
There is a difference between visiting and comforting the prisoner and evangelizing to them, and lying with dogs and getting up with fleas. Sadly most of us, myself included, don’t always do such a good job at understanding and acting on that difference.
Exactly right. God wants us to love one another. All of us have sinned and fall short of the glory of God. Anyone, no matter what they have done, can confess their sins and accept Jesus Christ as their personal savior. That is the only way to the Kingdom of Heaven. Good deeds are pleasing to God, but no matter how many good deeds you do, unless you accept Jesus as your lord and savior you are condemned to eternal hell.
