Immediately the thoughts of Judas sprang back to the foot-washing, and all the other marks of extraordinary tenderness with which Jesus had treated him. At the time he had thought, "He would not act like this if He knew all." Now, however, he realized that Jesus had acted in the full knowledge of all that had passed, and was passing in his heart. It must have struck him as extraordinary that the Master should continue to treat him thus when He had read the whole dark secret. Why did He not unmask and expose him? Why not banish him from His company? Why count him still on speaking terms? Not till afterward was he aware of Jesus' motive, nor did he detect the loving purpose which was laying siege to his stony heart as though to turn him from his evil purpose before it was too late. Once more the Lord made an effort to prove to him that though He knew all He loved him still, even to the end. It was the Jewish custom for one to dip a morsel in the common dish and pass it to another in token of special affection, so when He had dipped the sop, Jesus took and gave it to Judas, the son of Simon. He had previously answered John's whispered question, "Lord, who is it?" which had been suggested by a sign from Peter, by saying, "He it is to whom I shall give a sop when I have dipped it." But He did not give the token of love merely as a sign to John and Peter, but because He desired to assure Judas that, notwithstanding His perfect knowledge, His heart was full of tender affection. But when the sun strikes on a foetid pond, its rays, beneath which all creation rejoices, bring out the repulsive odors that otherwise had slept undiscovered; so the love of God is ever a savor of life unto life or of death unto death, and the very fervor of Christ's love seems to have driven Judas almost to madness. Shutting his heart against the Saviour, he opened it to Satan, who was waiting his opportunity. "After the sop, then Satan entered into him." Instantly the Master saw the change, and knew that He could do nothing more to save His disciple from the pit which he had digged for himself. Nothing could be gained by further delay. Jesus therefore said unto him, "That thou doest, do quickly."
