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, “A new 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.” Isaiah 64:6; Psalm 51:10; Ezekiel 36:26, 27. (DA 174.1) MC VC

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. (DA 174.2) MC VC

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.” John 3:14, 15. (DA 174.3) MC VC

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 destroying serpents was lifted up for their healing, so One made “in the likeness of sinful flesh” was to be their Redeemer. Romans 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. (DA 174.4) MC VC
