Let all those that seek Thee rejoice and be glad in Thee: and let such as love Thy salvation say continually, “Let God be magnified.” – Psalm 70:4

Sin was not pardoned absolutely; else justice had been dishonored; but sin was transferred from the guilty to the innocent One. “The Lord hath laid on Him the iniquity of us all.” When our iniquity was found upon the innocent Lamb of God, He was “smitten of God and afflicted,” as if He had been a sinner; He was made to suffer for transgressions not His own, as if they had been His own; and thus, mercy and justice met together, righteousness and grace kissed each other. Alas! there are many who fight against this plan, but I rejoice that I am surrounded by warm hearts who love it and would die for it. As for me, I know no other gospel and let this tongue be dumb rather than it should ever preach any other. Substitution is the very marrow of the whole Bible, the soul of salvation, the essence of the gospel, we ought to saturate all our sermons with it, for it is the life-blood of a gospel ministry. We must daily show how God the Judge can be “just, and yet the justifier of him that believeth.” We must declare that God has made the Redeemer’s soul a sacrifice for sin, making Him to be sin for us, who knew no sin, that we might be made the righteousness of God in Him. Our plain testimony must be, that “He was made a curse for us;” that “His own self bare our sins in His own body on the tree;” that “He was once offered to bear the sins of many;” and that “He was numbered with the transgressors, and He bare the sin of many.” About this we must never speak with bated breath, lest we be found unfaithful to our charge. And why, brethren, should we not joyfully proclaim this doctrine? for is it not the grandest, noblest, most divine, under heaven? The plan so adorns all the attributes of the Godhead and furnishes such a safe footing for a trembling conscience to rest upon, such a fortress, castle, and high tower for faith to rejoice in, that we cannot do otherwise than love it. The very way and plan of it is dearer to our souls than life itself. Oh, then let us always say, “Let God be magnified,” since He devised, arranged, and carried out this Godlike method of blending justice with mercy. C.H. Spurgeon
