This is the sum of the covenant, as it respecteth the letter, and the type, and the whole creation in general. But yet as to the spirit and gospel of it, the Holy Ghost must needs have a further reach, an intention of more glorious things, as may further be shewed anon.
"And I will establish my covenant with you." For you that are men, and especially the members of the church, have the most peculiar share therein.
"Neither shall all flesh be cut off any more by the waters of a flood." For because of my covenant which I establish with you, I will spare them also, and give them the taste of my mercy and goodness.
"Neither shall there any more be a flood to destroy the earth." This covenant therefore, is not of that nature as the covenant was which was made with Adam, to wit, a covenant of works, as the only conditions of life; for by that was the ground, for man's sin, accursed, accursed, and accursed again. But now the Lord goeth another way, the way of grace, and forgiveness of sins: Wherefore now, not the curse, but the mercy of God, comes in on the back and neck of sin, still sparing and forgiving man, the great transgressor, and the beast, &c. and the earth, for the sake of him.
Ver. 12, 13. "And God said, This is the token of the covenant which I make between me and you and every living creature that is with you, for perpetual generations. I do set my bow in the cloud, and it shall be for a token of a covenant between me and all the earth."
So then, the way to find out the covenant, what that is, it is to see if we can find out this token of it; to wit, the BOW, of which the rainbow is but a type. I find then by the scriptures, where this BOW is mystically spoken of, that the Lord Jesus Christ himself is encompassed with the bow. The first is this:
"And above the firmament that was over their heads was the likeness of a throne, as the appearance of a sapphire stone: and upon the likeness of the throne was the likeness, as the appearance of a man above upon it. And I saw, as the colour of amber, as the appearance of fire round about within it, from the appearance of his loins even upward, and from the appearance of his loins even downward, I saw as it were the appearance of fire, and it had brightness round about. As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD" (Eze 1:26-28), the man, the Lord's Christ, &c.
The second scripture is this. "I was in the Spirit: and, behold a throne was set in heaven, and one sat on the throne. And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald" (Rev 4:2,3). In these two texts there is mention of the rainbow, that was, not to be the covenant, but the token or sign thereof. Now then the covenant itself must needs be the man that was set in the midst of the bow upon the throne; for so he saith by the prophet, "I the LORD have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people" (Isa 42:6). The covenant therefore is Jesus Christ the Saviour, whom the bow in the clouds was a sign or a token of. So then the sum of the text is this, That God, for the sake of the Lord Jesus Christ, will not again all the days of the earth, bring an universal judgment upon the creature, as in the days of Noah, and of the old world he did; for Christ by the worth of his blood and righteousness hath pacified the justice of the law for sin. So then the whole universe standeth not upon a bottom of its own, but by the word and power of Christ (Heb 1:2,3). "The earth [said he] and all the inhabitants thereof are dissolved: I bear up the pillars of it" (Psa 75:3).
Quest. But how must Christ be reckoned of God, when he maketh him the poize against all the sin of the world.
The prophet tells us thus: He shall be the covenant of the people, or he shall be accounted the conditions and worth of the world; He shall be the covenant, or works, or righteousness of the people; for, He as the high-priest under the law, is set for the people to Godward; that is, he standeth always in the presence of God, as the complete obedience of the people. So then, so long as the Lord Christ bears up his mediatorship, God in justice will neither destroy the world, nor the things that are therein.
