For I will be merciful to their unrighteousness, and their sins and their iniquities I will remember no more. – Hebrews 8:12

There is such a truth, reality, and emphasis in the pardon of God as you can never find in the pardon of man; for though a man should forgive all you have done against him, if you have treated him very badly, yet it is more than you could expect that he should quite forget it, but the Lord says, “Their sins and iniquities will I remember no more for ever.” If a man has played you false, although you have forgiven him, you are not likely to trust him again. It is an old proverb, “Never ride a broken-knee’d horse,” and it is not a bad proverb either. But see how the Lord deals with His people. When Peter was set on his legs again he was a broken-knee’d horse enough, and yet see how gloriously the Lord rode that charger on the day of Pentecost. Did he not go forth conquering and to conquer? The Lord lets bygones be bygones so completely that He trusts pardoned souls with His secrets, for “the secret of the Lord is with them that fear Him”; and He entrusts some of us with His choicest treasures, for Paul said, “He hath put me in trust with the gospel, though I was a blasphemer.” He commits to our keeping that priceless casket which encloses the best hope of men, namely, the gospel of Jesus. “We have this treasure in earthen vessels.” This shows how perfect is our forgiveness,-nay, I must put it, how divine is the forgiveness which we have received. Let us rejoice in that grand promise which comes to us by the mouth of Jeremiah of old, “In those days, and in that time, saith the Lord, the iniquity of Israel shall be sought for, and there shall be none; and the sins of Judah, and they shall not be found: for I will pardon them whom I reserve.” Here is annihilation-the only annihilation I know of-the absolute annihilation of sin through the pardon which the Lord gives to His people. Let us sing it as though it were a choice hymn-“The iniquity of Israel shall be sought for, and there shall be none.” ~ C.H. Spurgeon

And you, being dead in your sins and the uncircumcision of your flesh, hath He quickened together with Him, having forgiven you all trespasses… – Colossians 2:13

All our transgressions are swept away at once, carried off as by a flood, and so completely removed from us that no guilty trace of them remains They are all gone! O ye believers, think of this, for the all is no little thing: sins against a holy God, sins against His loving Son, sins against gospel as well as against law, sins against man as well as against God, sins of the body as well as sins of the mind, sins as numerous as the sands on the sea shore, and as great as the sea itself: all, all are removed from us as far as the east is from the west. All this evil was rolled into one great mass, and laid upon Jesus, and having borne it all He has made an end of it for ever. When the Lord forgave us He forgave us the whole debt. He did not take the bill and say, “I strike out this item and that,” but the pen went through it all;-PAID. It was a receipt in full of all demands, Jesus took the handwriting which was against us and nailed it to His cross, to show before the entire universe that its power to condemn us had ceased for ever. We have in Him a full forgiveness.

And let it be remembered that this forgiveness which God has given us for Christ’s sake is an eternal forgiveness. He will never rake up our past offences and a second time impute them. He will not find us on an evil day, and say, “I have had great patience with you, but now will I deal with you after your sins.” Far otherwise, he that believeth in Jesus hath everlasting life, and shall never come into condemnation. Irreversible is the pardon of heaven. “The gifts and calling of God are without repentance.” He never repents what He has given, or forgiven. “Tis done, “tis done for ever: Jehovah absolves and the sentence stands fast for ever. “There is therefore now no condemnation to them which are in Christ Jesus.” “Who shall lay anything to the charge of God’s elect? It is God that justifieth. Who is he that condemneth?” Blessed be God for eternal pardon! ~ C.H. Spurgeon

I write unto you, little children, because your sins are forgiven you for His name’s sake. – 1 John 2:12

Are you in the number of the forgiven, my dear hearer? Hast thou believed in the Lord Jesus Christ? Then, as sure as you have believed, God for Christ’s sake hath forgiven you. Have you put your trust in the atoning sacrifice? Then God for Christ’s sake hath forgiven you. You have not begun to be a Christian, I hope, with the idea that one day, at some future period, you may obtain forgiveness. No. “God for Christ’s sake hath forgiven you.” Pardon is not a prize to be run for, but a blessing received at the first step of the race. If you have believed in Jesus your sin has all gone-all gone; all your sin has been erased from the records of the past, never to be mentioned against you for ever. The moment a sinner looks to Christ, the burden of his sin rolls from off his shoulders never to return. If Christ hath washed thee, (and He has if thou hast believed in Him) then thou art clean every whit, and before the Lord thou standest delivered from every trace of guilt. Pardon is not a matter of hope, but a matter of fact. Expectation looks for many a blessing, but pardon is a realized favour which faith holds in her hand even now. If Christ took thy load, thy load cannot remain on thine own back: if Christ paid thy debts, then they do not stand in God’s books against thee. How can they? It stands to reason that if thy Substitute has taken thy sin and put it away, thy sin lies no more on thee. God for Christ’s sake hath forgiven thee. Get hold of that grand truth, and hold it, though all the devils in hell roar at thee. Grasp it as with a hand of steel; grip it as for life: “God for Christ’s sake hath forgiven me,”-may each one of us be able to say that. ~ C.H. Spurgeon

To the praise of the glory of His grace, wherein He hath made us accepted in the Beloved. – Ephesians 1:6

It should never be forgotten that we originally fell by a representative. Adam stood for us, and he was our federal head. We did not fall personally at the first, but in our representative. Had he kept the conditions of the covenant we had stood through him, but, inasmuch as he fell, we fell in him. I pray you cavil not at the arrangement, because there lay the hope of our lace. The angels probably fell individually, one by one, and hence they fell irretrievably, -there was no restoring them: but as we fell in one Adam, there remained the possibility of our rising in another Adam; and therefore, in the fulness of time God sent forth His Son Jesus Christ, born of a woman, made under the law to become the second Adam. He undertook to remove our burdens and to fulfil the conditions of our restoration. According to covenant He must appear in our nature, and that nature in the fulness of time He assumed. He must bear the penalty: that He hath done in His personal suffering and death. He must obey the law: that He has done to the utmost. And now Christ Jesus, having borne penalty and fulfilled law, is Himself justified before God, and stands forth before God as the representative of all that are in Him. God for Christ’s sake has accepted us in Him, has forgiven us in Him, and looks upon us with love infinite and changeless in Him. This is how all our blessings come to us-in and through Christ Jesus; and if we are indeed in Him, the Lord doth not only forgive us our sin, but He bestows upon us the boundless riches of His grace in Him: in fact, He treats us as He would treat His Son; He deals with us as He would deal with Jesus. Oh, how pleasant to think that when the just God looks upon us it is through the reconciling medium- He views us through the Mediator. ~ C.H. Spurgeon
