"And God spake unto Noah, saying, Go forth of the ark." The same God that had said, "Make thee an ark" and "Come thou into the ark," now says, "Go forth of the ark." "And Noah went forth ... and builded an altar unto the Lord." All is simple obedience. There is the obedience of faith and the worship of faith: both go together. The altar is erected, where, just before; all had been a scene of death and judgment. The ark had borne Noah and his family safely over the waters of judgment. It had carried him from the old into the new world, where he now takes his place as a worshipper.[14] And, be it observed, it was "unto the Lord" he erected his altar. Superstition would have worshipped _the ark_, as being the means of salvation. It is ever the tendency of the heart to displace God by his ordinances. Now, the ark was a very marked and manifest ordinance; but Noah's faith passed beyond the ark to the God of the ark; and hence, when he stepped out of it, instead of casting back a lingering look at it, or regarding it as an object of worship or veneration, he built an altar unto the Lord, and worshipped him: and the ark is never heard of again. This teaches us a very simple, but, at the same time, a very seasonable lesson. The moment the heart lets slip the reality of God himself, there is no placing a limit to its declension; it is on the highway to the grossest forms of idolatry. In the judgment of faith, an ordinance is only valuable as it conveys God, in living power, to the soul; that is to say, so long as faith can enjoy Christ therein, according to his own appointment. Beyond this, it is worth just nothing; and if it in the smallest degree comes between the heart and his precious work and his glorious person, it ceases to be an ordinance of God, and becomes an instrument of the devil. In the judgment of superstition, the ordinance is every thing, and God is shut out; and the name of God is only made use of to exalt the ordinance, and give it a deep hold of the human heart, and a mighty influence over the human mind. Thus it was that the children of Israel worshipped the brazen serpent. That, which had once been a channel of blessing to them, because used of God, became, when their hearts had departed from the Lord, an object of superstitious veneration; and Hezekiah had to break it in pieces, and call it "a piece of brass." In itself it was only a "Nehushtan," but, when used of God, it was a means of rich blessing. Now, faith owned it to be what divine revelation said it was; but superstition, throwing, as it ever does, divine revelation overboard, lost the real purpose of God in the thing, and actually made a god of the thing itself.
