…for this my son was dead and is alive again
The same treatment the Lord accorded to Zacchaeus, the nefarious publican, who had defrauded people throughout the land. He may have heard some things from Christ directly and many more things from the report of others. He had gained the conviction that he could not go on in his sinful ways, but must amend his conduct. When the Lord was about to pass in the neighborhood, he mounted a sycamore-tree, because he wanted to see this holy Man. What did the Lord do? Catching sight of him in the tree, He called to him: “Zacchaeus, make haste and come down, for to-day I must abide at thy house.” Zacchaeus surely expected that the Lord would go over the record of his sins with him and hold up to him all the evil he had done. But Jesus did nothing of the kind. On the contrary in the house of Zacchaeus He said: “This day is salvation come to this house, forasmuch as he also is a son of Abraham.” It is Zacchaeus who says: “Behold, Lord, the half of my goods I give to the poor; and if I have taken anything from any man by false accusation, I restore him fourfold.” The Lord did not demand this of him, but his own conscience, first alarmed, but now quieted, demanded this joyful act of generosity to the poor from him. No doubt, he kept his promise.
The parable of the prodigal is another illustration. The Lord pictures him to us, after he had wasted everything he had with harlots, as returning to his father with a contrite heart. The father receives him without a word of censure, but falls upon his neck, kisses him, and exclaims: “Let us be merry; for this my son was dead and is alive again; he was lost and is found.” A joyous banquet is prepared, but not a word of reproof is spoken.
This attitude the Lord maintains even while hanging on the cross. Next to Him hangs one who has led an infamous life. The patient suffering of Christ has given him a new understanding, which he voices in these words: “We, indeed, are justly in this condemnation; for we receive the due reward of our deeds; but this man hath done nothing amiss.” Turning finally to the Lord, he says: “Lord, remember me when Thou comest into Thy kingdom.” He recognizes in Jesus the Messiah. And now observe that the Lord does not reply, “What! Thee I am to remember? Thee, who hast done so many wicked things?” No, He does not cast up his sins to him at all, but simply says: “To-day shalt thou be with Me in paradise.”
