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
