Sent to Glorify God

Jesus' brother encourage him to go to Jerusalem during the feast and gather a crowd and further his ministry. John tells us they say this because they don't believe in him. They want Jesus to prove himself.  On the other hand, Jesus is seeking the glory of the Father, not his own. He speaks the words and follows the timing of the Father. For this reason, he is eminently trustworthy. As sent disciples, we are sent by Jesus just like he was sent by the Father. So we seek only his glory, not our own.
