But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. -Matthew 12:36

If there is a God, He cannot let sin go unpunished. If He is really God, and the Judge of all the earth, He must have an utter abhorrence of all evil. It cannot be possible that He would think the same of the honest and the dishonest, of the moral and the immoral, of the sober and the drunken, of the truthful and the lying, of the gracious and the depraved. Such a god as that would be one whom men and women might rightly despise; but the true God, if we understand correctly who He is, must hate and abhor all sin. All evil must be utterly abhorrent to His pure and holy soul; and it is not only because He can do it, but because He must do it, that He will, one of these days, let loose the fury of His wrath against sin…This is the inevitable consequence of sin; there is nothing arbitrary about such a result. It is fixed, in the very nature of things, and every man and woman “…will have to give account on the day of judgment for every careless word they have spoken”  and for every sinful action, they must appear before Jesus Christ—the Judge of the living and the dead…Heaven and earth will pass away, but not one jot or tittle of God’s law can pass away until it is all fulfilled, and one part of that law requires that God punish all transgression, iniquity, and sin.

…To sin against the patience of Almighty God, is to sin with a vengeance. You do, as it were, defiantly put your finger into the very eye of God when you know that He sees you sin, and yet you go on sinning because He does not immediately take vengeance upon you for all your evil deeds. It is in great love that He restrains His wrath, for He is “slow to anger, abounding in love and faithfulness.” …Do not play with that patience of God which is allowing you time to seek the salvation of your soul. ~ C.H. Spurgeon

Who warned you to flee from the coming wrath? -Matthew 3:7

“Whoever does not believe stands condemned already because he has not believed in the name of God’s one and only Son” [John 3:18]; and yet again, “Whoever rejects the Son will not see life, for God’s wrath remains on him” [John 3:36]…This “coming wrath” will in part fall upon men and women at their death, but more fully at the day of judgment, and it will continue to flow over them for ever and ever.

Oh, this blessed plan of salvation by substitution—that Christ would take a poor, guilty sinner, and set him up there in the place of acceptance and joy at the right hand of God, and that, in order to be able to do so, Christ would say, “Here comes the great flood of almighty wrath; I will stand right where it is coming, and let it flow over Me” And you know that it did overflow Him until He sweat, as it were, great drops of blood, and more, until He cried aloud, “My God, my God why have you forsaken Me?” and still more, until He cried, “It is finished,” and He bowed His head, and gave up His spirit.

“He bore, that you might never bear, His Father’s righteous ire;” —

and so, suffering in your place, and putting you into the place of acceptance which He Himself so well deserves to occupy, He saves you from “the coming wrath.” ~ C.H. Spurgeon

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
