Good Friday.

"Yet it was the will of the Lord to crush him; he has put him to grief; when his soul makes an offering for sin, he shall see his offspring, he shall prolong his days; the will of the Lord shall prosper in his hand. Out of the anguish of his soul he shall see and be satisfied; by his knowledge shall the righteous one, my servant, make many to be accounted righteous, and he shall bear their iniquities. Therefore I will divide him a portion with the many, and he shall divide the spoil with the strong, because he poured out his soul to death and was numbered with the transgressors; yet he bore the sin of many, and makes intercession for the transgressors." Isaiah 53:10-12

"Oh, to see the dawn of the darkest day: Christ on the road to Calvary. Tried by sinful men, torn and beaten, then nailed to a cross of wood.
This, the pow'r of the cross: Christ became sin for us; took the blame, bore the wrath—we stand forgiven at the cross."
