Jesus is in absolute agony, sweating blood, as he prays honestly with the Father. What is the cup he is so grieved about? It is the cup of the wrath of God. Every sin is like a drop into a cup. We pour the sin in. God, at the end of this life, pours out commensurate wrath. Yet Jesus submits his will to the Father’s; he exchanges places with us on the cross and drinks every single drop of the wrath of God. The cross is where the love of God is most clearly seen: wrath was poured out on Jesus, and love was poured out for us.
