Hanli draws out two crucial truths in this initial part of the 'High Priestly Prayer' where Jesus is praying to his Father.
Firstly the Lord prays that God would glorify the Son, so that the Son might glorify the Father, because the hour has come. This hour refers singularly in John's gospel to Christ's crucifixion. How could this terrible hour, the most humiliating moment of Jesus's life show God's glory? Because only through the cross do we see that God is able and willing to save to the uttermost, every sinner who draws near through faith in Jesus.
Secondly, the Lord shows what the true essence of eternal life is. Eternal life is to personally and intimately know the one true God and Jesus Christ whom he has sent. Have you come to this personal relationship with God through faith in Christ crucified? There is no greater question than this!
