While they were sticklers for the letter of the law, they were constantly violating its spirit. Their great need was that very change which Christ had been explaining to Nicodemus,--a new moral birth, a cleansing from sin, and a renewing of knowledge and holiness.
There was no excuse for the blindness of Israel in regard to the work of regeneration. Under the inspiration of the Holy Spirit, Isaiah had written, "We are all as an unclean thing, and all our righteousnesses are as filthy rags." David had prayed, "Create in me a clean heart, O God; and renew a right spirit within me." And through Ezekiel the promise had been given, "Anew heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. And I will put My Spirit within you, and cause you to walk in My statutes." Isa. 64:6; Ps. 51:10; Ezek. 36:26, 27.
Nicodemus had read these scriptures with a clouded mind; but he now began to comprehend their meaning. He saw that the most rigid obedience to the mere letter of the law as applied to the outward life could entitle no man to enter the kingdom of heaven. In the estimation of men, his life had been just and honorable; but in the presence of Christ he felt that his heart was unclean, and his life unholy.
Nicodemus was being drawn to Christ. As the Saviour explained to him concerning the new birth, he longed to have this change wrought in himself.
By what means could it be accomplished? Jesus answered the unspoken question: "As Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: that whosoever believeth in Him should not perish, but have eternal life."Here was ground with which Nicodemus was familiar. The symbol of the uplifted serpent made plain to him the Saviour's mission. When the people of Israel were dying from the sting of the fiery serpents, God directed Moses to make a serpent of brass, and place it on high in the midst of the congregation. Then the word was sounded throughout the encampment that all who would look upon the serpent should live. The people well knew that in itself the serpent had no power to help them. It was a symbol of Christ. As the image made in the likeness of the 175destroying serpents was lifted up for their healing, so One made "in the likeness of sinful flesh" was to be their Redeemer. Rom. 8:3. Many of the Israelites regarded the sacrificial service as having in itself virtue to set them free from sin. God desired to teach them that it had no more value than that serpent of brass. It was to lead their minds to the Saviour.
Whether for the healing of their wounds or the pardon of their sins, they could do nothing for themselves but show their faith in the Gift of God.
They were to look and live.
Those who had been bitten by the serpents might have delayed to look. They might have questioned how there could be efficacy in that brazen symbol.
They might have demanded a scientific explanation. But no explanation was given. They must accept the word of God to them through Moses. To refuse to look was to perish.
Not through controversy and discussion is the soul enlightened. We must look and live. Nicodemus received the lesson, and carried it with him. He searched the Scriptures in a new way, not for the discussion of a theory, but in order to receive life for the soul. He began to see the kingdom of heaven as he submitted himself to the leading of the Holy Spirit.
