Sing, O ye heavens; for the LORD hath done it…for the LORD hath redeemed Jacob and glorified Himself in Israel. – Isaiah 44:23

We may lay peculiar force upon the word, “The Lord hath done it,” for He has finished the work. In the matter of the redemption of His people nothing remains to be done. There is no mortgage on the church of God to be ultimately discharged, the Lord has made us His unencumbered freehold, and we are His own portion for ever. There is not a little left of human merit for the sinner to work out for himself, or some little point in which the work of salvation is incomplete; but “The Lord hath done it.” No, brethren, even the fringe of the robe of righteousness is all there; you have not a thread to add to it, it is without seam, and woven from the top throughout, all of one piece. Consummatum est. “It is finished;” every type fulfilled, every commandment kept, every sin abolished, the wrath of God and everything that hindered put away.

A very important part of the song, however, lies in the fact that what God has done glorifies Himself. Infinite mercy and condescending love reflect glory upon God…In redemption you see all the attributes of God, blended in harmony, shining with benignant radiance, not with the flash and flame of Sinai, but with the soft beams of peace and love from Calvary. God is never so gloriously seen as at the cross; no, not even amidst the flaming seraphim do the saints above enjoy such a view of God as when they see Him in the wounds of Jesus and putting their finger into the print of the nails, exclaim with transport, “My Lord and my God.” ~ C.H. Spurgeon

Sing, O ye heavens; for the LORD hath done it.. – Isaiah 44:23

It is sweet to reflect that redemption is an accomplished fact. It is not “The Lord will do it,” but “The Lord hath done it.” …I have to-day to speak of a matter of history-“The Lord hath done it”; He who was the offended one has provided a propitiation; His own deed of transcendent grace has scattered the thick clouds of sin and poured eternal day upon the darkened earth. Jesus has bled and died and vanquished sin thereby. Our glorious Samson lay asleep in the Gaza of the tomb, and His foes thought they had Him fast for ever; but He awoke before the morning light, and He pulled up the gates of death and hell, post and bar and all, and carried them away, leading captivity captive. He hath done it, our divine Deliverer has spoiled death and the grave for us. “Sing, O ye heavens: shout, ye lower parts of the earth.” The Breaker is gone up before us, and our King is at the head of us; He hath broken up and cleared a pathway straight from the tomb to the throne of God. Glory be to His name; He has done it.

Then sinner, listen. Your sin can be blotted out…O man, those fetters are not, after all, eternal, they may be snapped; the bars in yonder window may be torn out so that you can escape into liberty. Begin to sing, then! Alas, I know you will not because I bid you, nor at any man’s bidding, till grace sets you free. The only thing to make you sing is for you to realize salvation; and oh, may you do so at this moment by believing in Jesus. Have done with everything but Christ and drop into His arms! Rest in Him; trust Him; depend upon Him, and all is well, and then will you cry aloud, “Sing, O ye heavens, for the Lord hath done it.”~ C.H. Spurgeon

For sin shall not have dominion over you: for ye are not under the law, but under grace… But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life. – Romans 6:14,22

Of redemption, redemption by price and by power, we are bidden to sing, a redemption so pre-eminently desirable that we can never sufficiently value it; a redemption which has delivered us from sin, of all slaveries the worst. “Sin shall not have dominion over you;” Christ has effectually redeemed you from its tyrannic sway. You enjoy also deliverance from the curse of the law, by Christ’s being made a curse for us, as it is written, “Cursed is every one that hangeth on a tree.” You are blest with deliverance from misery; wherever there is sin misery is sure to follow, but Jesus has borne the penalty for your sins and turned it aside from you. You are delivered from carking care, and unbelieving anxiety; the peace of God, which passeth all understanding, keeps your heart and mind by Jesus Christ. And you are delivered from death and hell. Let this thought thrill you with delight: in your ear can never ring the doleful sentence, “Depart, ye cursed,” for you there is no bottomless pit, no fire which cannot be quenched, no worm which never can die. Christ has delivered you; you are no longer slaves to sin and victims to death, for you are set free from the thraldom of Satan’s power, who hath the power of death. He may tempt, but he cannot force; he may provoke, but he cannot subdue. Christ has undone the devil’s work, has cast him down from his throne, and torn up his stronghold; his empire over you is ended, never to be renewed. In you who have believed the Lord has set up His throne, and there will He reign for ever. Glory be to God for this. The Lord’s redemption is the theme of ceaseless praise, for it is a redemption which brings in its train hope, holiness, and heaven, deliverance from sin, likeness to Christ, and eternal glory with Christ. Sing, O heavens, and be joyful, O earth! ~ C.H. Spurgeon

Sing, O ye heavens; for the LORD hath done it… – Isaiah 44:23

O sing unto the LORD a new song; for he hath done marvellous things: His right hand, and His holy arm, hath gotten Him the victory. – Psalm 98:1

The great subject of joy is redemption-the redemption of God’s Israel. This is a stupendous work. It was a simple matter for man to sell himself into slavery, but to redeem him was another matter. This is the work; this is the labor! To redeem man from his iniquity is a work which all the cherubim and seraphim could not have accomplished, a work indeed which all creatureship would have failed to perform. My brethren, our slavery was terrible, and the price of deliverance was far beyond mountains of silver and gold. The redemption of the soul is precious; “it cannot be valued with the gold of Ophir, with the precious onyx, or the sapphire. The gold and the crystal cannot equal it: and the exchange of it shall not be for jewels of fine gold.” As there needed a price, so there was needed a power to redeem; for with a high hand and an outstretched arm must Israel be brought out of Egypt; and where could such power be found? Neither angel nor archangel possessed it, and as for the sons of man, the insects which dance through a summer’s eve are not more feeble. Hopeless is human bondage unless the malice and craft and power of Satan can be matched by love and wisdom and force superior at all points. The price has been found; the power has been displayed. Sing, O ye heavens, for the Lord has found a ransom! We were not redeemed with corruptible things, as silver and gold, but with the precious blood of Christ, and that price has effectually set us free. Break forth into singing, ye mountains, for the Lord hath also found the power: His own right hand and His holy arm has gotten Him the victory! He has brought up His people out of the house of bondage and made them free indeed. ~ C.H. Spurgeon
