For while we were still weak, at the right time Christ died for the ungodly. Indeed, rarely will anyone die for a righteous person -- though perhaps for a good a person someone might actually dare to die. But God proves his love for us in that while we were still sinners Christ died for us (Rom 6.6-8).
The absolute togetherness and oneness in being and doing between the crucified Jesus Christ and the Lord God is of supreme importance for our belief in the Love of God. That was the truth made clear by St Paul in his Epistle to the Romans, when he had in mind the Old Testament account of the 'sacrifice' of Isaac by Abraham, when Abraham showed that he loved God more than he loved himself. And so St Paul wrote: 'If God is for us, who can be against us? He who did not spare his own Son, but gave him up for us all -- how will he not also, along with him, graciously give us all things?' (Rom 8:31-32). Jesus is God's very own Son, his only begotten Son -- one who came to us out of the Father's Life who belonged to his very Heart and innermost Self. And when the Father did not spare his own Son but freely delivered him up for us all in atoning sacrifice, the Cross became a window into the innermost heart of God and the nature of his Love. It tells us that God loves us more than he loves himself.
That is what the oneness in being and act between Jesus Christ and God, between the incarnate Son and the Father, reveals to us: that our heavenly Father loves us more than he loves himself -- and we are assured of an infinite love from which nothing in life or death can ever separate us. The love of the Lord Jesus in giving himself for us on the Cross for our salvation, where the infinite sacrifice of the Father and the infinite sacrifice of the Son are forever bound up indivisibly together, assures us that the eternal God, let it be repeated, loves us more than he loves himself. God loves us with an infinite love from which nothing in life or death can ever separate us. That is the love incarnate in the Lord Jesus (T.F. Torrance in A Passion for Christ: The Vision that Ignites Ministry, p. 14).
