See also Jn. In vs. 4 Jesus speaks about glorifying the Father, clothing, the Father in splendor. Jesus glorified God by completing the work which the Father gave Him to do. Everything from conception until the ascension. He came not to be served, but to serve, to give His life as a ransom.
Men glorify themselves because of their sinful pride.
For Thine is the kingdom and the power and the glory, forever and ever. Every believer has seen Jesus' glory and will see it forever in heaven. No one killed Jesus. He died willingly. I have the authority to give it up and I have authority to take it again.
