Strictly speaking, salvation requires forgiveness, and forgiveness requires repentance. God is not about to populate Heaven with unrepentant sinners. But God is able to forgive a lot, so we should at least be prepared to as well. And going “eye for an eye” on someone does no one any good.
All I’m saying is that if someone has wronged me, and wants my forgiveness, he has to ask for it, and he may have to make it right.
Otherwise, fine. MY aim is to waste no more thought on him. I am through with that person, and it would be best for them if they never needed anything from me.
I have to admit though, I do have a lot of trouble with the whole “vengeance is mine’ thing and have spent a lot of time in prayer about nit.
