Leonardo da Vinci was one of the outstanding intellects of all history, for he was great as a draftsman, an engineer, and a thinker. Just before he commenced work on his “Last Supper” he had a violent quarrel with a fellow painter. So enraged and bitter was Leonardo that he determined to paint the face of his enemy, the other artist, into the face of Judas, and thus take his revenge and vent his spleen by handling the man down in infamy and scorn to succeeding generations. The face of Judas was therefore one of the first that he finished, and everyone could easily recognize it as the face of the painter with whom he had quarreled.
But when he came to paint the face of Christ, he could make no progress. Something seemed to be baffling him, holding him back, frustrating his best efforts. At length he came to the conclusion that the thing which was checking and frustrating him was the fact that he had painted his enemy into the face of Judas. He therefore painted out the face of Judas and commenced anew on the face of Jesus, and this time with the success which the ages have acclaimed.
You cannot at one and the same time be painting the features of Christ into your own life, and painting another face with the colors of enmity and hatred.
