Here's a thought from Fulton Sheen's book "Life of Christ" to consider this Easter weekend:
"Those who saw the empty grave were bidden to go to Peter who had tempted Our Blessed Lord from the Cross and had three times denied him. Sin and denial could not choke Divine love. Paradoxical though it was, the greater the sin, the less the belief; and yet the greater the repentance from sin, the greater the belief. It was to the lost sheep panting in the wilderness that He came; it was the publicans and the harlots, the denying Peters and the persecuting Pauls to whom the most persuasive entreaties of love were sent."
