At the Last Supper, Jesus glorifies his Father and speaks of his own glory, the glory of the cross which exemplifies his great love for us sinners and the reversal of our condemnation. The greatest gift a son can give to his father is to be obedient to him. Jesus was obedient to his Father until death, even death on the cross the ultimate glorification. The essence of our faith is the knowledge that God is our Father. Through the cross, Jesus made it possible for all of us to recognize this truth. Jesus also speaks of the Father bringing glory to the Son through the great mystery of the incarnation and the cross. There is no greater proof of Gods love for us than Christs cross. In the cross we see a love that is unconditional, complete, perfect.
Jesus prays to the Father for his disciples that he would soon be leaving behind. He is concerned as a mother for her children, to keep them, to keep us believers, safe and protected because we belong to the Father who, in turn, endorsed us to Jesus. We belong to God because we believe in Jesus. How generous God is. And we are so undeserving.
