One of the central themes throughout John's Gospel is the concept that Jesus has been sent by the Father, or sometimes stated He is here to do the Will of the one who sent Him. We read this in yesterday's and today's Gospel passages and will continue to encounter it leading up to Easter. Jesus even makes it one the main topics of conversation during the Last Supper. John preserves the dinner conversation in what has affectionately now referred to as the Farwell Discourse (Jn 14-17). In it Jesus wants His Apostles to believe that Jesus was sent by the father, to do the will of the Father, and ultimately bring us back to the Father. This is one of the main teachings of our Faith and John makes sure we hear it throughout his Gospel. The most famous of these passages being John 3:16 "For God so loved the world that He sent his only Son so that all who believe in Him might not perish but have eternal life."
