Behold the Lamb of God, which taketh away the sin of the world.
When Adam sinned, God took a lamb and shed its blood to cover his sin. That day the principle of substitution was established: “The just for the unjust” (1 Peter 3:18). God told Noah to take two of each unclean animal, but seven of each clean animal, so that there would be a blood sacrifice when the world started again. In the Old Testament tabernacle, God arranged the furniture (the altar, the laver, the mercy seat, etc.) in the shape of a cross: four pieces down and three pieces across. Then He told Moses to sprinkle each piece with the blood of a lamb. For 1,400 years God looked down and saw a blood-stained cross in the midst of His people. How wonderful!
But one day John the Baptist pointed to Jesus and said, “Behold the Lamb of God which taketh away the sin of the world” (John 1:29). Did you hear that? Not just the sin of an individual or a family or a nation—but the sin of the whole world! That includes you and me. Listen: “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” (John 3:16).
Today He’s waiting to save you from your sins; all you have to do is call on Him—He’ll do the rest!
