Ancient Israel had lived for nearly 2000 years under the charter of their national existence which, as we read in the Old Testament, was given on Sinai amidst thunderings and lightnings, Now, therefore, if ye will obey My voice indeed, and keep My covenant, then ye shall be a peculiar treasure unto Me above all people; for all the earth is Mine, and ye shall be unto Me a kingdom of priests and an holy nation.'
And that covenant, or agreement, or treaty, on the part of God, was ratified by a solemn act, in which the blood of the sacrifice, divided into two portions, was sprinkled, one half upon the altar, and the other half, after their acceptance of the conditions and obligations of the covenant, on the people, who had pledged themselves to obedience.
And now, here is a Galilean peasant, in a borrowed upper room, within four-and-twenty hours of His ignominious death which might seem to blast all His work, who steps forward and says, I put away that ancient covenant which knits this nation to God. It is antiquated. I am the true offering and sacrifice, by the blood of which, sprinkled on altar and on people, a new covenant, built upon better promises, shall henceforth be.'
What a tremendous piece of audacity, except on the one hypothesis that He that spake was indeed the Word of God; and that He was making that which Himself had established Of old, to give way to that which He establishes now! The new covenant which Christ seals in His blood, is the charter, the better charter, under the conditions of which, not a nation but the world may find an external salvation which dwarfs all the deliverances of the past. That idea of a covenant confirmed by Christ's blood may sound to many hearers dry and hard. But if you will try to think what great truths are wrapped up in the theological phraseology, you will find them very real and very strong. Is it not a grand thought that between us and the infinite divine Nature there is established a firm and unmovable agreement? Then He has revealed His purposes; we are not left to grope in darkness, at the mercy of peradventures' and probablies ; nor reduced to consult the ambiguous oracles of nature or of Providence, or the varying voices of our own hearts, or painfully and dubiously to construct more or less strong bases for confidence in a loving God out of such hints and fragments of revelation as these supply. He has come out of His darkness, and spoken articulate words, plain words, faithful words, which bind Him to a distinctly defined course of action. Across the great ocean of possible modes of action for a divine nature He has, if I may so say, buoyed out for Himself a channel, so as that we know His path, which is in the deep waters. He has limited Himself by the utterance of a faithful word, and we can now come to Himwith His own promise, and cast it down before Him, and say: Thou hast spoken, and Thou art bound to fulfil it.' We have a covenant wherein God has shown us His hand, has told us what He is going to do and has thereby pledged Himself to its performance.
And, still further, in order to get the full sweetness of this thought, to break the husk and reach to the kernel, you must remember what, according to the New Testament, are the conditions of this covenant. The old agreement was, If ye will obey My voice and do My commandments, then,'--so and so will happen. The old condition was, Do and live; be righteous and blessed!' The new condition is: Take and have; believe and live!' The one was law, the other is gift; the one was retribution, the other is forgiveness. One was outward, hard, rigid law, fitly graven with a pen of iron on the rocks for ever'; the other is impulse, love, a power bestowed that will make us obedient; and the sole condition that we have to render is the condition of humble and believing acceptance of the divine gift. The new covenant, in the exuberant fulness of its mercy, and in the tenderness of its gracious purposes, is at once the completion and the antithesis of the ancient covenant with its precepts and its retribution.
And, still further, this new covenant,' of which the essence is God's bestowment of Himself on every heart that wills to possess Him; this new covenant, according to the teaching of these words of my text and of the symbol to which they refer, is ratified and sealed by that great sacrifice. The blood was sprinkled on the altar; the blood was sprinkled on the people, which being translated into plain, unmetaphorical language is simply this, that Christ's death remains for ever present to the divine mind as the great reason and motive which modifies His government, and which ensures that His love shall ever find its way to every seeking soul. His death is the token; His death is the reason; His death is the pledge of the unending and the inexhaustible mercy of God bestowed upon each of us. He that spared not His own Son, shall He not with Him also freely give us all things?' The outward rite with its symbol is the exhibition in visible form of that truth, that the blood of Jesus Christ seals to the world the infinite mercy of God.
And, on the other hand, that same blood of the covenant, sprinkled upon the other parties to the treaty, even our poor sinful hearts, binds them to the fulfilment of the condition which belongs to them. That is to say, by the power of that sacrifice there are evoked in our poor souls, faith, love, surrender. It, and it alone, knits us to God; it, and it alone, binds us to the fulfilment of the covenant. My brother, have you entered into that sweet, solemn, sacred alliance and union with God? Have you accepted and fulfilled the conditions? Is your heart sprinkled with the blood so freely shed for you'; and have you thereby been brought into living alliance with the God who has pledged His being and His name to be the all-sufficient God to you?
