“Again the next day after John stood, and two of his disciples; and looking upon Jesus as He walked, he saith, Behold the Lamb of God.”- John 1:35-36

The world was lost; God must punish sin; He sent His Son to take our sin upon Him that He might honor the law of God and establish God’s government by being obedient to the law, and yielding Himself up to the death-penalty. He whom Jehovah loves beyond all else came to earth, became a man, and, as a man, was obedient unto death of the cross. It is He who is called in our text “the Lamb of God,” the one Sacrifice for man’s sin. There is no putting away of sin without sacrifice; there is only one Sacrifice that can put away sin, and that is, Jesus Christ the righteous. He is divine, yet human; Son of God, yet son of Mary. He yielded up His life, “the Just for the unjust,” the Sinless for the sinful, “that He might bring us to God,” and reconcile us to the great Father. That is the story, and whosoever believeth in Him shall live. Any man, the world over, who will trust himself to Christ, God’s great Sacrifice, shall be saved, for this is our continual witness, “He that believeth on the Son hath everlasting life.” “For God so loved the world, that He gave His only-begotten Son, that whosoever believeth in Him should not perish but have everlasting life.”

I want to entreat men, who have looked elsewhere, now to turn their eyes away from the fruitless search after peace and life, and to come and “Behold the Lamb of God, which taketh away the sin of the world.” May the Spirit of God open their eyes, and incline their hearts, that they may look unto Him and live! ~ C.H. Spurgeon
