This is something I struggle with but if I have an expectation that Christ forgives me as promised, shouldn’t I do the same as commanded by Christ?
Yes.
God wants us to.
Hurt runs deep though and can destroy us if we let it.
Yes, the Lord’s Prayer makes that very clear.
Forgive us our tresspasses AS WE FORGIVE those who trespass against us.
Forgiving others is actually more beneficial for us, than for those that we forgive.
In fact, our forgiveness doesn’t absolve those we forgive.
Only God’s forgiveness can do that.
But it could very well could inspire those who have offended us to be repentant and then ask God to forgive them.
After all, the Bible makes it clear that all sin is against God, so it is Him we need to ask for forgiveness.
I believe it was David who said “It is you oh God against whom I have sinned”
Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
KJV; Psalm 51:4
