From JC Ryle, Expository Thoughts on the Gospels, commenting on Mark 10:
Let us mark, lastly, in this passage, the language which our Lord uses in speaking of His own death. He says, “The Son of Many came to give His life a ransom for many.”
This is one of those expressions which ought to be carefully treasured up in the minds of all true Christians. It is one of the texts which prove incontrovertibly the atoning character of Christ’s death. That death was no common death, like the death of a martyr, or of other holy men. It was the public payment by an Almighty Representative of the debt of sinful man to a holy God. It was the ransom which a Divine Surety undertook to provide, in order to procure liberty for sinners, tied and bound by the chain of their sins. By that death Jesus made a full and complete satisfaction for man’s countless transgressions. he bore our sins in His own body on the tree. The Lord on Him the iniquity of us all. When He died, He died for us. When He suffered, He suffered in our stead. When He hung on the cross, He hung there as our Substitute. When His blood flowed, it was the price of our souls.
