John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
[The Desire Of Ages. pp 465>466] In the words, “I am the light of the world,” Jesus declared Himself the Messiah. The aged Simeon, in the temple where Christ was now teaching, had spoken of Him as “a light to lighten the Gentiles, and the glory of Thy people Israel.” Luke 2:32. In these words he was applying to Him a prophecy familiar to all Israel. By the prophet Isaiah, the Holy Spirit had declared, “It is too light a thing that Thou shouldest be My servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give Thee for a light to the Gentiles, that Thou mayest be My salvation unto the end of the earth.” Isaiah 49:6
This prophecy was generally understood as spoken of the Messiah, and when Jesus said, “I am the light of the world,” the people could not fail to recognize His claim to be the Promised One.
To the Pharisees and rulers this claim seemed an arrogant assumption. That a man like themselves should make such pretensions they could not tolerate. Seeming to ignore His words, they demanded, “Who art Thou?” They were bent upon forcing Him to declare Himself the Christ. His appearance and His work were so at variance with the expectations of the people, that, as His wily enemies believed, a direct announcement of Himself as the Messiah would cause Him to be rejected as an impostor.
But to their question, “Who art Thou?” Jesus replied, “Even that which I have also spoken unto you from the beginning.” John 8:25. That which had been revealed in His words was revealed also in His character. He was the embodiment of the truths He taught. “I do nothing of Myself,” He continued; “but as My Father hath taught Me, I speak these things. And He that sent Me is with Me: the Father hath not left Me alone; for I do always those things that please Him.” He did not attempt to prove His Messianic claim, but showed His unity with God. If their minds had been open to God's love, they would have received Jesus.
Among His hearers many were drawn to Him in faith, and to them He said, “if ye continue in My word, then are ye My disciples indeed; and ye shall know the truth, and the truth shall make you free.” These words offended the Pharisees. The nation's long subjection to a foreign yoke, they disregarded, and angrily exclaimed, “We be Abraham's seed, and were never in bondage to any man: how sayest Thou, Ye shall be made free?” Jesus looked upon these men, the slaves of malice, whose thoughts were bent upon revenge, and sadly answered, “Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.” They were in the worst kind of bondage,—ruled by the spirit of evil.
John 8:23 And he said unto them, Ye are from beneath; I am from above: ye are of this world; I am not of this world. 24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins. 25 Then said they unto him, Who art thou? And Jesus saith unto them, Even the same that I said unto you from the beginning. 26 I have many things to say and to judge of you: but he that sent me is true; and I speak to the world those things which I have heard of him.
May God add His blessing to the study of His word. "Good night" and God bless!
