"And Noah builded an altar." Although this altar be the first that we read of, yet forasmuch as there was before a blessed church, and also an open profession of godliness, together with offering sacrifice, in all probability this was not the first altar that was builded unto the Lord. Besides, we read not of any immediate revelation, from which Noah had light and instruction to build it. The text only saith, he built an altar unto the Lord; which may be aptly expounded, according as he was wont in the other world.

This altar was a type of Christ, as capacitated to bear the sin of the world (for the altar was it, upon which the sacrifices were burnt;) wherefore it, in mine opinion, in special respected his Godhead, by the power of which he offered himself, that is, his flesh. Again it is said, "The altar sanctifieth the gift" (Matt 23:19). So did the Godhead the humanity of Christ, through which "eternal Spirit, he offered himself without spot to God" (Heb 9:14). By this altar then this blessed man preached to his family the Godhead and eternity of Christ.

"And took of every clean beast, and of every clean fowl." These beasts and fowls were types of the flesh of the Son of God, as Paul in the ninth and tenth chapters to the Hebrews affirms; wherefore by this act he also preached to his family the incarnation of the Lord Christ, how that "in the fulness of time" he should in our flesh offer himself a sacrifice for us; for as all the ordinances of the New Testament ministration preach to us, That Christ is come; so all the ordinances of worship under the Old Testament preached to them that were under it, Christ, as yet TO come.

"Of every clean beast and of every clean fowl." This was to shew, That when Christ did come, he should not take hold of the Jew, and exclude the Gentile; but that in his flesh he should present unto God EVERY clean beast, and EVERY clean fowl; that is, all the elect, both of Jew and Gentile (Acts 10:11-16).

And it was requisite that this by Noah should be preached, because the whole world was yet in his family; from whence, at the multiplication of men, if through their rebellion and idolatry they lost not this doctrine, they might to all their offspring preach the Lord Jesus.

Wherefore, the doctrine of the gospel, had the world been faithful, might have been to this day retained amongst them that now are the most barbarous people.[37]

Ver. 21. "And the Lord smelled a sweet savour;

These words more fully shew, that this sacrifice of Noah was a type of the offering up of the body of Jesus Christ, he being said to be that blessed sacrifice that is as perfume in the nostrils of God: "He gave himself for us an offering and a sacrifice to God for a sweet-smelling savour" (Eph 5:2). Besides, this offering of Noah was a burnt-offering to God; which burning signified, the curse of God, which Christ was made in his death for us. Wherefore, the burnt offerings were all along a type of him; as by reading the epistle to the Hebrews you may see: "It is the burnt-offering, [saith God,] because of the burning upon the altar all night unto the morning, and the fire of the altar shall be burning in it" (Lev 6:9). Which was a type of the fire of the law, and the guilt of sin, that Christ, when he offered himself, should undergo for the sins of man.

"And the Lord smelled a sweet savour." This signifies the content and satisfaction that for the sin of the world, God should have by the offering upon of his Son for us upon the cross: Wherefore, he is said to be now "in Christ, reconciling the world unto himself, not imputing their trespasses unto them" (2 Cor 5:19).

Now it is observable, That Noah was a man of faith long before this. Hence note two things.
