“Behold! The Lamb of God…” – John 1:29,36

How was the Lamb of God first seen in the world? It was the case of the lamb for one man, brought by one man for himself, and on his own behalf. You all know that I refer to Abel, who was a shepherd, and brought of the firstlings, of his flock, that is, a lamb, and he brought this lamb for himself, and on his own account, that he might be accepted by God, and that he might present to God an offering well-pleasing in His sight. Cain brought of the fruit of the ground as an offering to God. I think that there was a difference in the sacrifice, as well as in the man bringing it, for the Holy Ghost says little about the difference of the man, but He says, “By faith Abel offered unto to God a more excellent sacrifice than Cain,” and he was accepted because he brought a more excellent sacrifice. The one sacrifice was bloodless, the fruit of the ground, the other was typical of Christ, the Lamb of God, and was therefore accepted: “and the Lord had respect unto Abel, and to his offering.”

Now, beloved, our first view of Christ usually is here, to know Him ourselves. I am a sinner, and I want to have communion with my God; how shall I obtain it? I am guilty, I am sinful; how shall I draw near to the holy God? Here is the answer. Take the Lord Jesus Christ to be yours by faith and bring Him to God; you must be accepted if you bring Christ with you. The Father never repelled the Son, nor one who was clothed with the Son’s righteousness, or who pleaded the Son’s merit. Come you, as Abel came, not with fruits of your own growing, but with the sacrifice of blood, with Christ the holy Victim, the spotless Lamb of God, and so coming, whoever you may be, you shall be acceptable before God by faith. Now, behold Him, each one of you for yourself! ~ C.H. Spurgeon
