If there is someone in your life, from whom you are withholding forgiveness, that is not okay. If there is someone in your life, and you are saying “Well, God will forgive, but I CANNOT,” then that is not okay, and be warned: it is not the sin of the other, but your OWN lack of forgiveness with which you must be concerned! If you find too much fault with another to forgive them, know today that God looks at you with wide wonder as the most curious of his people: willing to take his forgiveness for yourself, yet never willing to share it with others.
