New Park Street Pulpit · Sermon No. 69
Delivered on Sabbath Morning, March 2, 1856, New Park Street Chapel, Southwark.
“These are the two covenants.”—Galatians 4:24.
THERE cannot be a greater difference in the world between two things than there is between law and grace. And yet, strange to say, while the things are diametrically opposed and essentially different from each other, the human mind is so depraved, and the intellect, even when blessed by the Spirit, has become so turned aside from right judgment, that one of the most difficult things in the world is to discriminate properly between law and grace. He who knows the difference, and always recollects it—the essential difference between law and grace—has grasped the marrow of divinity. He is not far from understanding the gospel theme in all its ramifications, its outlets, and its branches, who can properly tell the difference between law and grace. There is always in a science some part which is very simple and easy when we have learned it, but which, in the commencement, stands like a high threshold before the porch. Now, the first difficulty in striving to learn the gospel is this. Between law and grace there is a difference plain enough to every Christian, and especially to every enlightened and instructed one; but still, when most enlightened and instructed, there is always a tendency in us to confound the two things. They are as opposite as light and darkness, and can no more agree than fire and water; yet man will be perpetually striving to make a compound of them—often ignorantly, and sometimes wilfully. They seek to blend the two, when God has positively put them asunder.
We shall attempt this morning to teach you something of the allegories of Sarah and Hagar, that you may thereby better understand the essential difference between the covenants of law and of grace. We shall not go fully into the subject, but shall only give such illustrations of it as the text may furnish us. First, I shall want you to notice the two women, whom Paul uses as types—Hagar and Sarah; then I shall notice the two sons—Ishmael and Isaac; in the third place, I shall notice Ishmael’s conduct to Isaac; and I shall conclude by noticing the the different fates of the two.
I. First, we invite you to notice THE TWO WOMEN—Hagar and Sarah. It is said that they are the types of the two covenants; and before we start we must not forget to tell you what the covenants are. The first covenant for which Hagar stands, is the covenant of works, which is this: “There is my law, O man; if thou on thy side wilt engage to keep it, I on my side will engage that thou shalt live by keeping it. If thou wilt promise to obey my commands perfectly, wholly, fully, without a single flaw, I will carry thee to heaven. But mark me, if thou violatest one command, if thou dost rebel against a single ordinance, I will destroy thee for ever.” That is the Hagar covenant—the covenant propounded on Sinai, amidst tempests, fire and smoke—or rather, propounded, first of all, in the garden of Eden, where God said to Adam, “In the day that thou eatest thereof thou shalt surely die.” As long as he did not eat of the tree, but remained spotless and sinless, he was most assuredly to live. That is the covenant of the law, the Hagar covenant. The Sarah covenant is the covenant of grace, not made with God and man, but made with God and Christ Jesus, which covenant is this: “Christ Jesus on his part engages to bear the penalty of all his people’s sins, to die, to pay their debts, to take their iniquities upon his shoulders; and the Father promises on his part that all for whom the Son doth die shall most assuredly be saved; that seeing they have evil hearts, he will put his law in their hearts, that they shall not depart from it, and that seeing they have sins, he will pass them by and not remember them any more for ever.” The covenant of works was, “Do this and live, O man!” but the covenant of grace is, “Do this, O Christ, and thou shalt live, O man!” The difference of covenants rests here. The one was made with man, the other with Christ; the one was a conditional covenant, conditional on Adam’s standing, the other is a conditional covenant with Christ, but as perfectly unconditional with us. There are no conditions whatever in the covenant of grace, or if there be conditions, the covenant gives them. The covenant gives faith, gives repentance, gives good works, gives salvation, as a purely gratuitous unconditional act; nor does our continuance in that covenant depend in the least degree on ourselves. The covenant was made by God with Christ, signed, sealed, and ratified, in all things ordered well.
Now come and look at the allegory. First, I would have you notice, that Sarah who is the type of the new covenant of grace, was the original wife of Abraham. Before he knew anything about Hagar, Sarah was his wife. The covenant of grace was the original covenant after all. There be some bad theologians who teach that God mad man upright, and made a covenant with him; that man sinned, and that as a kind of afterthought God mad a new covenant with Christ for the salvation of his people. Now, that is a complete mistake. The covenant of grace was made before the covenant of works; for Christ Jesus, before the foundation of the world, did stand as its head and representative; and we are said to be elect according to the foreknowledge of God the Father, through the obedience and sprinkling of the blood of Jesus. We, long ere we fell, were loved of God; he did not love us out of pity to us, but he loved his people, considered purely as creatures. He loved them when they became sinners; but when he started with them he considered them as creatures. He allowed them to fall into sin, to show forth the riches of his grace, which existed before their sin. He did not love them and choose them from among the rest, after their fall, but he loved them beyond their sin, and before their sin. He made the covenant of grace before we fell by the covenant of works. If you could go back to eternity, and ask which is the oldest born, you would hear that grace was born before law—that it came into the world long before the law was promulgated. Older even than the fundamental principles which guide our morals is that great fundamental rock of grace, in covenant made of old, long ere seers preached the law, and long ere Sinai smoked. Long before Adam stood in the garden God had ordained his people to eternal life, that they might be saved through Jesus.
