Be gentle and forbearing with one another and, if one has a difference (a grievance or complaint) against another, readily pardoning each other; even as the Lord has [freely] forgiven you, so must you also [forgive]. Col. 3:13 [AMP]
He forgave us. Past tense…once and for all. All people for all time.
The blood of Jesus is the basis for the forgiveness of God. He gave Himself in order that God the Father could forgive us so the the relationship between and God and man would be restored.
AND He forgave us SO that we could forgive each other.
The word of God commands us to forgive one another. If you love God, you will obey God and you will forgive….period.
This sounds harsh and hard but it is really the highest form of love. He gave so that we could give, he forgave so that we could forgive.
