“The Son of man
Came
Not to be served,
But to serve.
He came
To give his life
As a ransom for many.”
καὶ γὰρ ὁ Υἱὸς τοῦ ἀνθρώπου οὐκ ἦλθεν διακονηθῆναι ἀλλὰ διακονῆσαι καὶ δοῦναι τὴν ψυχὴν αὐτοῦ λύτρον ἀντὶ πολλῶν
There is something similar to this in Matthew, chapter 20:28, almost word for word. Mark indicated that Jesus said that the Son of Man came not to be served (καὶ γὰρ ὁ Υἱὸς τοῦ ἀνθρώπου οὐκ ἦλθεν διακονηθῆναι), but to serve others (ἀλλὰ διακονῆσαι). He was going to give his life (καὶ δοῦναι τὴν ψυχὴν αὐτοῦ) as a ransom for many people (λύτρον ἀντὶ πολλῶν). This ransom or freeing of slaves was a divine liberation from the slavery of sin. Quite often in the Old Testament, Yahweh said that he was going to save his people, the Israelites. Jesus was going to pay the penalty of death. Thus, he ransomed a great number of people from their sins or their debts. Thus, this is an indication of redemptive salvation.
