Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage. – Galatians 5:1

All those who trust in works never are free, and never can be, even could they be perfect in good works. Even if they have no sin, still they are bond-slaves, for when we have done all that we ought to have done, God is not our debtor, we are debtors still to Him, and still remain as bond-slaves. If I could keep all God’s law, I should have no right to favour, for I should have done no more than was my duty, and be a bond-slave still. The law is the most rigorous master in the world, no wise man would love its service; for after all you have done, the law never gives you a “Thank you,” for it, but says, “Go on, sir, go on.!” The poor sinner trying to be saved by law is like a blind horse going round and round a mill, and never getting a step further, but only being whipped continually; yea, the faster he goes, the more work he does, the more he is tired, so much the worse for him. The better legalist a man is, the more sure he is of being damned; the more holy a man is, if he trust to his works, the more he may rest assured of his own final rejection and eternal portion with Pharisees. Hagar was a slave; Ishmael, moral and good as he was, was nothing but a slave, and never could be more. Not all the works he ever rendered to his father could make him a free-born son. Sarah never was a slave. She might be sometimes taken prisoner by Pharoah, but she was not a slave then; her husband might sometimes deny her, but she was his wife still; she was soon owned by her husband, and Pharoah was soon obliged to send her back. So the covenant of grace might seem once in jeopardy, and the representative of it might cry, “My Father, if it be possible, let this cup pass from me;” but it never was in real hazard. And sometimes the people under the covenant of grace may seem to be captives and bond-slaves; but still they are free. Oh! that we knew how to “stand fast in the liberty wherewith Christ hath made us free.”~ C.H. Spurgeon

For it is written that Abraham had two sons: the one by a bondwoman, the other by a freewoman. – Galatians 4:24

For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. -Romans 8:29

Before (Abraham) 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 made man upright, and made a covenant with him; that man sinned, and that as a kind of afterthought God made 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.~ C.H. Spurgeon

And the children of Israel journeyed from Rameses to Succoth, about six hundred thousand on foot that were men, beside children. And a mixed multitude went up also with them; and flocks, and herds, even very much cattle. – Exodus 12:37, 38

O ye mixed multitude! ye are the ruin of the churches; ye set us a lusting; the pure Israelite’s blood is tainted by union with you; you sit as God’s people sit, and yet you are not His people; you hear as God’s people hear, and yet you are “in the gall of bitterness and in the bonds of iniquity.”

My dear hearers, do try yourselves, to see whether you are real Israelites. Oh! could Christ say to you, “Behold an Israelite indeed, in whom there is no guile.” Have you the blood on your door-post? Have you eaten of Jesus? Do you live on Him? Do you have fellowship with Him? Has God the Holy Ghost brought you out of Egypt? or have you come out yourself? Have you found refuge in His dear cross and wounded side? If you have, rejoice, for Pharaoh, himself, cannot bring you back again; but if you have not, I pray my Master to dash your peace into atoms, fair and lovely as it may be; I beseech Him to send the winds of conviction and the floods of His wrath, that your house may fall now, rather than it should stand to your death, and then, in the last solemn hour, the edifice of your own hands should totter. Mixed multitude! hear ye this! ye assembled gatherings of professors! “Examine yourselves, whether ye be in the faith; prove your-own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?” But if He be not in you, then are ye reprobates still, whom God abhorreth. The Lord bring all His people out of Egypt, and deliver all His children from the house of bondage.~ C.H. Spurgeon

It came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the Lord went out from the land of Egypt.” -Exodus 12:51

Our dear Arminian friends think that some of the Lord’s people will not come out of Egypt, but will be lost at last. Ah! well, as good Hart says-

“If one poor saint may fall away,
It follows so may all;”

and none of us are safe and secure. Therefore, we do not give way to that. But all the hosts came out of Egypt, every one of them; not a soul was left behind…They all came out, every one of them; there was not one left behind…So beloved, if you are “the meanest lamb in Jesus’ fold,” you are “one in Jesus now;” though you have very little learning, and very little common sense, you will come out of Egypt. If the Lord has put you there in bondage, and you have been made to groan there, He will make you sing by-and-by, when you are redeemed from it. There is no fear of your being left behind; for if you were, Pharoah would say, “He delivered the strong ones, but He was not able to fetch out the weak;” and then there would be laughter in hell against the might and omnipotence of God. They all came out… He hath not only delivered His people, but they have gone out with flying colours, taking their shields with them. Stand and admire and love the Lord, who thus delivers all His people. ~ C.H. Spurgeon

And it came to pass the selfsame day, that the LORD did bring the children of Israel out of the land of Egypt by their armies. -Exodus 12:51

“Ask them whence their victory came,
They with united breath
Ascribe their victory to the Lamb,
Their triumph in His death.”

One agonizing sacrifice, one death on Calvary, one bloody sweat on Gethsemane, one shriek of “It is finished.” consummated all the work of redemption. Oh! the precious blood of Christ! I love it when I think it saves one sinner; but oh! to think of the multitude of sinners that it saves! Beloved, we do not think enough of our Lord Jesus Christ; we have not half such an estimation of His precious person as we ought to have. We do not value His blood at the right price. Why, poor sinner, thou art saying this morning, “This blood cannot save me.” What! not save thee, when it is engaged to save thousands upon thousands, and myriads of myriads? Shall the shepherd who gathereth the whole flock together, and leadeth them unto the pastures lose a single lamb? Thou sayest, perhaps, “I am so little.” For that very reason then, thou dost not want so much of His power to take care of thee. “But,” says one, “I am so great a sinner.” Aye, then, so much the better, for He “came to save sinners, of whom I am chief,” said Paul; and He came to save thee. Ah! do not fear, ye sons of God; He who brought the Israelites all out in one night can bring you all out, though you are in the veriest bondage…this unworthy hand shall take the hand of the blessed St. Paul; they shall all be in heaven, shall all be redeemed, shall all be saved; but, mark you, through one sacrifice, one covenant, one blood, one Passover. ~ C.H. Spurgeon
