Sometimes I ask myself: “Is it right to repent now and then?”
No. Maybe this answer surprises you, but you should not repent “now and then”.
Every time the Holy Spirit convicts you of sin, you should ask for forgiveness, and repent. That is stop going in the wrong direction and return to God, every time, and as soon as you realize you did something wrong.
