and if I hand my body over so that I may boast
but do not have love, I gain nothing.
-- 1 Cor 12:31-13:13
By embracing in his human heart the Father's love for men, Jesus "loved them to the end", for "greater love has no man than this, that a man lay down his life for his friends." In suffering and death his humanity became the free and perfect instrument of his divine love which desires the salvation of men. Indeed, out of love for his Father and for men, whom the Father wants to save, Jesus freely accepted his Passion and death: "No one takes [my life] from me, but I lay it down of my own accord." Hence the sovereign freedom of God's Son as he went out to his death.
