Space will not allow of my entering upon the question as to the precise relation of these final words to the rest of the verse, but their relation to the great purpose of the whole verse is plain enough. It has come to be very unfashionable nowadays to talk about the covenant. People think that it is archaic, technically theological, far away, from daily life, and so on and so on. I believe that Christian people would be a great deal stronger, if there were a more prominent place given in Christian meditations to the great idea that underlies that metaphor. And it is just this, that God is under obligations, taken on Him by Himself, to fulfil to a poor, trusting soul the great promises to which that soul has been drawn to cleave. He has, if I might use such a metaphor, like some monarch, given a constitution to His people. He has not left us to grope as to what His mind and purpose may be. Across the infinite ocean of possibilities, He has marked out on the chart, so to speak, the line which He will pursue. We have His word, and His word is this: After those days, saith the Lord, I will make a new covenant. I will write My law on their inward parts. I will be their God, and they shall be My people.' So the definite, distinct promise, in black and white, so to speak, to every man and woman on the face of the earth, is Come into the bonds of the covenant, by trusting Me, and you will get all that I have promised.'
And that covenant is, as my text says, sealed by the blood.' Which, being turned into less metaphorical English, is just this, that God's infinite pro-pension of beneficence towards each of us, and desire to clothe us in garments of radiant purity, are, by Christ's death, guaranteed as extending to, and working their effects on, every soul that trusts Him. What does that death mean if it does not mean that? Why should He have died on the Cross, unless it were to take away sin?
But the blood of the covenant does not mean only the death by which the covenant is ratified. We shall much misapprehend and narrow New Testament teaching, if we suppose that. The blood is the life.' There is further suggested, then, by the expression, that the vital energy, with which Jesus Christ came from the dead as the Shepherd of the sheep, is the power by which God makes us perfect in every good work to do His will, working in us that which is well-pleasing in His sight.'
So, two practical counsels may close my words. See that you aspire as high as God's purpose concerning you, and do not be content with anything short of the, at least, incipient and progressive accomplishment in your characters and lives, of that great prayer. Again, see that you use the forces which, by the Cross and the Resurrection and the Ascension, are set in motion to make that wondrous possibility a matter-of-fact reality for each of us; and whoever you are, and whatever you have been, be sure of this, that He can lift you from the mud and cleanse you from its stains, and set you at His own right hand in the heavenly places. For the name, and the risen Shepherd, and the blood of the everlasting covenant, make a threefold cord, not to be quickly broken, and able to bear the weight of the loftiest hopes and firmest confidence that we can hang upon it.
