The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.
-2 Peter 3:9, NIV
The implication of 2 Peter 3:9 is without repentance God does not forgive but allows the sinner to perish for their sins.
A desire for a cheater to come to repentance is not only wise but godly. It reflects God’s heart for this individual.
Insisting on repentance before forgiveness seems–according to this Bible verse–to be the proper spiritual order of things.
That said, I do not advocate holding out forever for a cheater to repent. You may die before that happens with some of these characters.
Instead, I advocate working towards giving them over to God’s justice and wisdom. He is better at dealing with their sin than we ever will be.
Plus, we need to remember God has “skin” in the “game.” He is a GOOD Father who witnessed the traumatic injury of His beloved child–i.e. you, faithful spouse. Trust that He is angry over such abuse and will do what is right!
We can trust God with our hurts and our abuser.
