3. We have the greatest slight of that will of God which is most for his honor and his greatest pleasure. It is the nature of man, ever since Adam, to do so (Hos. vi. 6, 7). God desired mercy and not a sacrifice; the knowledge of himself more than burnt offering; but they, like men as Adam, have transgressed the covenant, invade God’s rights, and not let him be Lord of one tree. We are more curious observers of the fringes of the law than of the greater concerns of it. The Jews were diligent in sacrifices and offerings, which God did not urge upon them as principals, but as types of other things; but negligent of the faith which was to be established by him. Holiness, mercy, pity, which concerned the honor of God, as governor of the world, and were imitations of the holiness and goodness of God, they were strangers to. This is God’s complaint {a111} (Isa. i. 11, 12, xvi. 17). We shall find our hearts most averse to the observation of those laws which are eternal, and essential to righteousness; such that he could not but command, as he is a righteous Governor; in the observation of which we come nearest to him, and express his image more clearly; as those laws for an inward and spiritual worship, a supreme affection to him. God, in regard of his righteousness and holiness of his nature, and the excellency of his being, could not command the contrary to these. But this part of his will our hearts most swell against, our corruption doth most snarl at; whereas those laws which are only positive, and have no intrinsic righteousness in them, but depend purely upon the will of the Lawgiver, and may be changed at his pleasure (which the other, that have an intrinsic righteousness in them, cannot), we better comply with, than that part of his will that doth express more the righteousness of his nature;[183] such as the ceremonial part of worship, and the ceremonial law among the Jews. We are more willing to observe order in some outward attendances and glavering devotions, than discard secret affections to evil, crucify inward lusts and delightful thoughts. A “hanging down the head like a bullrush” is not difficult; but the “breaking the heart,” like a potter’s vessel, to shreds and dust (a sacrifice God delights in, whereby the excellency of God and the vileness of the creature is owned), goes against the grain; to cut off an outward branch is not so hard as to hack at the root. What God most loathes, as most contrary to his will, we most love: no sin did God so severely hate, and no sin were the Jews more inclined unto, than that of idolatry. The heathen had not changed their God, as the Jews had changed their glory (Jer. ii. 11); and all men are naturally tainted with this sin, which is so contrary to the holy and excellent nature of God. By how much the more defect there is of purity in our respects to God, by so much the more respect there is to some idol within or without us, to humor, custom, and interest, &c.
