Ransom in Mark 10

For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”
(Mark 10:45 ESV)

To bring this discussion to a close: the natural meaning of the ransom saying is that Jesus' death was in the stead of the many, He was to give His life instead of their lives, and we see no reason for abandoning this interpretation. It may or may not be easy to integrate this into some theory of the way the atonement works, but either way we are not justified in evading the plain sense of the Greek. (Morris, Leon.
