"Now when He was in Jerusalem at the passover, during the feast, many believed on His name, beholding His signs which He did. But Jesus did not trust Himself unto them, for that He knew all men, and because He needed not that any one should bear witness concerning man; for He Himself knew what was in man. Now there was a man of the Pharisees, named Nicodemus, a ruler of the Jews: the same came unto Him by night, and said to Him, Rabbi, we know that Thou art a teacher come from God: for no man can do these signs that Thou doest, except God be with Him. Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born anew, he cannot see the kingdom of God. Nicodemus saith unto Him, How can a man be born when he is old? can he enter a second time into his mother's womb, and be born? Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born anew. The wind bloweth where it listeth, and thou hearest the voice thereof, but knowest not whence it cometh, and whither it goeth: so is every one that is born of the Spirit."--JOHN ii. 23-iii. 8.
The first visit of Jesus to Jerusalem was not without considerable effect on the popular mind. Many who saw the miracles He did believed that He was a messenger from God. They saw that His miracles were not the clever tricks of an impostor, and they were prepared to listen to His teaching and enrol themselves as members of the kingdom He came to found. Yet our Lord did not encourage them. He saw that they misunderstood Him. He recognised their worldliness of heart and of aim, and did not admit them to the intimacy He had established with the five simple-minded Galileans. The Jerusalem Jews were glad to fall in with one who seemed likely to do honour to their nation, and their belief in Him was the belief men give to a statesman whose policy they approve. The difference between them and those who rejected Christ was not a difference of disposition such as exists between godly and ungodly men, but consisted merely in the circumstance that they were convinced that His miracles were genuine. Had our Lord encouraged these men they would ultimately have been disappointed in Him. It was better that from the first they should be stimulated to reflect on the whole matter by being coldly received by the Lord.
It is always a point that calls for reflection: we have to consider not only whether we have faith in Christ, but whether He has faith in us--not only whether we have committed ourselves to Him, but whether that committal is so genuine that He can build upon and trust it. Can He count upon us for all service, for fidelity in times when much is needed? Thoroughgoing confidence must always be reciprocal. The person you believe in so utterly that you are entirely his, believes in you and trusts himself to you--his reputation, his interests are safe in your keeping. So is it with Christ. Faith cannot be one-sided here any more than elsewhere. He gives Himself to those who give themselves to Him. They who so trust Him that He is sure they will follow Him even when they cannot see where He is going; they who trust Him, not in one or two matters which they see He can manage, but absolutely and in all things,--to these He will give Himself freely, sharing with them His work, His Spirit, His reward.
