After describing all that death is and what it signifies, Rev. Herman Hoeksema applies it to Jesus Christ, the Son of God who died on the cross at Calvary:
And so He died.
O, yes, it was necessary that He, too, should die the physical death. He might not simply suffer the agonies of death on the cross, in order then to be revived or glorified in the sight of the enemies. He must bear the wrath of God to the end. The sentence of God in physical death is that the sinner has absolutely forfeited every right to his existence in the world. This sentence must be executed upon Christ also. God takes away His whole earthly house. His very name perishes. His body, too, collapses, and He gives up the ghost. Also upon Him the sentence is pronounced that He is unworthy to exist on the earth.
Only, as the Head of His people, He agrees with the sentence of God with all His heart. He makes of death an act. His life He lays down even as God takes it. His spirit He commends to God, His body He delivers over into the place of corruption. His name and position He freely offers up to the righteousness of God. And in delivering up His soul unto death He confesses: ‘Thou, Father, art just and righteous, when Thou judgest that the sinner has no right to be, should be utterly destroyed from the earth, and should sink into everlasting desolation. Take my life, my name, my all. Freely I offer it in love to Thee. For even now it is my meat to do Thy will!’
…Only His death, the death of the Son of God Himself in human nature, could be so deep, so precious in the sight of God, that by His obedience many could be made righteous. Only when the death of the cross is the death of the Son of God can we have the assurance that our sins are blotted out for ever, and that in Christ we have the righteousness of God by faith.
