Charles Spurgeon Commentary John 10:16-18

"And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice: and they shall become one flock, one shepherd. Therefore doth the Father love me, because I lay down my life, that I may take it again. No one taketh it away from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment received I from my Father." — John 10:16-18 (ASV)

Them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd. Therefore doth my Father love me, because I lay down my life, that I might take it again. No man taketh it from me, but I lay it down of myself.

Christ's death was to be the act of his own free will, as well as of the violence of wicked men.
