Oh my God, I am heartily sorry for having offended Thee, and I detest all my sins because I dread the loss of Heaven, and I fear the pains of Hell, and Thy just punishments on earth. But most of all, I seek to detest my sins simply because they offend Thee, my God, because Thou alone art all-good and deserving of all my love. I firmly resolve, with the help of Thy Grace to avoid the near occasion of sin, to do penance, and to amend my life. Amen.
I'm a crossover from Vatican II, so you may see a few minor differences, but that is basically the Act of Contrition said by the penitent when we are absolved from our sins.
“Contrition” not “Contribution” - sorry, long day, tired eyes...

Christians can come to God and do that sort of thing any time they feel the need to. No need to wait until it's time to go to confession and tell a priest.
It's me and God time with a heart to heart discussion with my Heavenly Father, Creator of the universe and not a stand in for Him. I talk to HIM directly.
