Since the time that the first human pair, smitten by the sense of guilt, hid themselves from the presence of the Lord God among the trees of the garden, and their first-born son, with his hands reddened by a brother's blood, declared that his punishment was greater than he could bear, down to the ignoble disciple who, after selling the life of his Master for filthy lucre, unable to bear the upbraidings of conscience, went and hanged himself, the consciousness of having broken God's Law and exposed one's self to the righteous displeasure of the great Lawgiver, has haunted and pained man everywhere and at all times, and filled him with a fear which all his own efforts and every human appliance is powerless to remove. Why go farther than our own selves? Is there a person here who can declare that never for a moment has his soul's surface been disturbed by feelings of regret, who can truthfully affirm that he has never known what it means to experience remorse for duty neglected, for wrong spoken or done? We have sought on previous Sundays to drive home to your conscience the terrors of the law on matters of the Sixth, Seventh, and Eighth Commandments; and do you mean to say that in a review of your past life you have no slightest pain of self-reproach along these lines? If not, then your spirit has been cast in a different mold from all others, or your memory and conscience are both fast asleep. I take it that all are ready to acknowledge not only that there is a law, a law written in God's Word, as well as in your own hearts, but that we have also broken that law time and again, and thereby--to quote the familiar words of our Catechism--"have we exposed ourselves to God's wrath and displeasure, temporal death, and eternal damnation." This is the A B C of Christianity. And is there a way of escape, as in the case of Egypt's death and destruction? no possibility of its being said: "I will pass over you"? Ah, it is here that we come to the heart and center of our holy religion, its pith and core, its Holiest of Holy. Sprinkled upon the headpieces and the two posts of their doors was the blood, God's own sacred mark. A lamb, none over a year old, none with the slightest taint or blemish upon it, was made to yield up its life in sacrifice to secure that blood. Need I inform you what that typified, of whom that lamb was a type and shadow? That unblemished lamb of sacrifice referred to Christ, "the Lamb of God which taketh away the sin of the world." That innocent blood which turned aside the angel of death foreshowed the blood of Christ, who through the Spirit offered Himself without spot to God. Yonder upon that post with its two beams, reddened by crimson drops, is the fulfillment, the realization, of it all. Simple, is it not?
