Christ hath redeemed us from the curse of the law, being made a curse for us… – Galatians 3:13

Some of you, my dear friends, will be able to follow me in your experience, while I just remind you how it was, that in your salvation Christ removed the curse. You will agree with me when I say that the removal of the curse from us is done in a moment. It is an instantaneous thing. I may stand here one moment under the curse; and if the Spirit look upon me, and I breathe a prayer to heaven-if by faith I cast myself on Jesus-in one solitary second, ere the clock hath ticked, my sins may be all forgiven. Hart sung truly, when he said-

“The moment a sinner believes,
And trusts in his crucified God,
His pardon at once he receives,
Salvation is full through His blood.”

We do not say that the great work of conversion is instantaneous; that may take some time; for Christ commences in the heart a work, which is to be carried on through life in sanctification; but the justification, the taking away the curse, is done in a single moment. “Unwrite the curse,” says God. It is done. The acquittal is signed and sealed; it taketh not long.

“Fully discharged by Christ I am,
From sin’s tremendous curse and blame.”

We may be fully absolved in a moment.~ C.H. Spurgeon

But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe. – Galatians 3:22

There are many persons who think that the curse of God upon those who are undeniably wicked is, of course, right; but that the curse of God upon those who for the most part appear to be excellent, and who may have sinned but once, as an act of injustice. We answer, “Nay, when God pronounces the curse, He doth it justly; He is a God of justice; ‘just and right is He.'” And mark thee, man, if thou art condemned, it shall be by the strictest justice; and if thou hast sinned but once, the curse is righteous when it lights upon thy head. Dost thou ask me how this is? I answer, Thou sayest thy sin is little; then, if the sin be little, how little trouble it might have taken thee to have avoided it! If thy transgression be but small, at how small an expense thou mightest have refrained from it! Some have said, “Surely the sin of Adam was but little; he did but take an apple.” Ay, but in its littleness was its greatness. If it was a little thing to take the fruit, with how little trouble might it have been avoided! And because it was so small an act, there was couched within it the greater malignity of guilt. So, too, thou mayest never have blasphemed thy God, thou mayest never have desecrated His Sabbath; yet, insomuch as thou hast committed a little sin, thou art justly condemned, for a little sin hath in it the essence of all sin; and I know not but that what we call little sins may be greater in God’s sight than those which the world universally condemns, and against which the hiss of the execration of humanity continually rises. I say, God is just, although from His lips should rush thunders to blast the entire universe; God is just, although He curses all. Tremble, man, and “kiss the Son, lest He be angry, and ye perish by the way, when His wrath is kindled but a little. Blessed are all they that put their trust in Him.”~ C.H. Spurgeon

“Christ hath redeemed us from the curse of the law, being made a curse for us; for it is written, Cursed is every one that hangeth on a tree.”- Galatians 3:13

Paul says, “the law is holy, but I am carnal; sold under sin.” In all we ever say concerning justification by faith, we never intend to lower the opinion which our hearers have of the law, for the law is one of the most sublime of God’s works. There is not a commandment too many; there is not one too few; but it is so incomparable, that its perfection is a proof of its divinity…But while the law is glorious, it is never more misapplied than when it is used as a means of salvation. God never intended men to be saved by the law. When He proclaimed it on Sinai, it was with thunder, fire, and smoke; as if He would say, “O man, hear My law; but thou shalt tremble while thou hearest it.” Hear it! It is a law which hath the blast of a terrible trumpet, even like the day of destruction, of which it is but the herald, if thou offendest it, and findest none to bear the doom for thee. It was written on stone; as if to teach us that it was a hard, cold, stony law-one which would have no mercy upon us, but which, if we break it, would fall upon us, and dash us into a thousand pieces. O ye who trust in the law for your salvation! ye have erred from the faith; ye do not understand God’s designs; ye are ignorant of every one of God’s truths… It was intended by its thunders to crush every hope of self-righteousness, by its lightnings to scathe and demolish every tower of our own works, that we might be brought humbly and simply to accept a finished salvation through the one mighty Mediator who has “finished the law, and made it honorable, and brought in an everlasting righteousness,” whereby we stand, stand complete before our Maker at last, if we be in Christ. ~ C.H. Spurgeon
