Chapter 17 records Jesus’ farewell prayer.  This prayer embraces every
aspect of his mission, and it begins with an request that God be
glorified in his death and resurrection.

God the Son had perfect and complete glory before the world began.  He
has always lived in unapproachable light, and has always been
perfectly honorable (1 Tim 6:16).  When God the Son became man, he
remained perfectly glorious in himself, but he veiled that glory in
human flesh, so that he appeared to be a man like any other.  At
times, however, Jesus’ inward glory would peek through, such as the
time on the mountain when “his face shone like the sun, and his
clothes became white as light” (Matthew 17:2).  Jesus is praying that
he would once again be clothed in splendor, such as he was before the
world began.

There is a sense in which Jesus’ inward glory can be seen on the
cross.  Though he did not shine with light, he did display God’s glory
to the world as he died for our sins.  In the cross, God the Father is
glorified through God the Son.

The glory of God in the cross of Jesus Christ is made clear whenever
someone believes in Jesus.  As Jesus seeks and saves those sheep that
the Father has given to him, he brings glory to God.  We should praise
him for redeeming us.
