The bitter truth is that as a married person, If you cheat on your partner, No matter your prayers, Believe me, You can't be forgiven without letting your partner know.

Marriage is not boyfriend and girlfriend that you can hide anything. Marriage is a covenant. it makes two to become one.
So Why will you hide anything from yourself?

If you have ever cheated on your partner, You need to tell them. What matters is your approach. that's where wisdom is needed.

Marriage is not just between you and God, Its between you and your partner. and when you cheat, You've wronged your partner, You must ask for their forgiveness too. Believe me if you don't, You Will lose heaven.

This is the true Gospel.
I know a Pastor, who once cheated on his wife years ago, After like twenty years, God reminded him and told him that he would never be forgiven if he doesn't tell his wife. it was quite a challenge but he later told his wife, And She forgave him. Simple.

If you think it's difficult to report yourself to your spouse after cheating, then don't cheat.
Your body is not your own, you can't do anything and go and meet God, Go and meet your spouse.

Thank You.
