Think about about what you said for a second. If you confess and don't actually change your mind about it, is your lip service of any value to God? If you actually do change your mind about sin and, of course, change your ways as well, confessing your sin to God, isn't that the heart of what confession is?
There is no difference between confession and repentance. God already knows what you did. What God is looking for is your return to walking in the light like John says. Confession is intended to be used for those who are ready to forsake whatever sin it is they are genuinely repenting of.
1 John 1
7But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
