The quick answer to these questions is that no matter how we are to God and to each other, we will always remain children of God and brothers and sisters to each other. As such, we are meant to love God and everybody else, irrespective of how we behave. And it is forgiveness which is the ultimate form of love.
If God, in Christ, loves us so much that he became man and went all the way to offer his life for us, and if we are children of God who are supposed to be like God, then we too should have a love for God and for one another that is boundless.
Christ’s boundless love for us is shown not only in the fact that he offered his life for us—and as St. John said, “Greater love has no than this, that a man lays down his life for his friends” (Jn 15,13)—but he also offered forgiveness to those who crucified him. (cfr. Lk 23,34)
We should just learn how to be forgiving the way God in Christ is always forgiving us. And the reason is because by always forgiving, we liken ourselves with God, with Christ, who is the pattern of our humanity and the savior of our damaged humanity. Forgiving is the ultimate act of love which is the very essence of God and which is also intended for us since we are supposed to be God’s image and likeness.
Thus, we have to learn to be forgiving always of others, no matter how undeserving we feel they are of forgiveness. That’s how God forgave us. He took the initiative. He offered forgiveness and continues to do so if only to bring us back to him.
The awareness of this truth should also help us to develop the attitude to forgive one another as quickly as possible, since that is the only way we can learn to love. When we find it hard to forgive others, it is a clear sign that we are full of ourselves, are self-righteous, proud and vain.
We have to continually check on our attitude towards others because today’s dominant culture is filled precisely by the viruses of self-righteousness, that feeling that we are superior to others, etc. We have to do constant battle against that culture that undermines our duty to be always forgiving.
Obviously, to be always forgiving, we need to make a lot of sacrifice since we have to conquer our pride. Forgiveness is a real game-changer since with it we would be willing to let go of whatever hurt and anger we may have. It actually takes a huge weight off our shoulders.
Pride often stems from the feeling that we have been wronged or disrespected. But with forgiveness, we can manage to let go of that feeling, enabling us to be stronger than our ego. It’s not actually about letting someone off the hook. The guilty still has to face the consequences of his acts. But with forgiveness, we free ourselves from negative vibes.
With forgiveness, we can manage to be at peace with anyone even as we continue to sort out things to fix whatever problem or issue we may have at hand.
