The seed of salvation had begun to spring up in him, for he desired to see Jesus, having never seen Him. For if he had seen Him, he would long since have given up the Publican's wicked life. No one that sees Jesus can remain any longer in wickedness. But there were two obstacles to his seeing Him. The multitude not so much of men as of his sins prevented him, for he was little of stature.
But he discovered a good device; running before he climbed up into a sycamore, and saw Him whom he had long wished for, i.e. Jesus, passing by. Now Zacchaeus desired no more than to see, but He who is able to do more than ve ask for, granted to Him far above what he expected; as it follows, And when Jesus came to the place, he looked up, and saw him. He saw the soul of the man striving earnestly to live aholy life, and converts him to godliness.
