The one who speaks on his own authority seeks his own glory; but the one who seeks the glory of him who sent him is true, and in him there is no falsehood.  John 7:18

Of all the leaders and teachers on all levels throughout human history, there has been none whose motives have been purer than Jesus.  Though He rightfully deserved to be exalted and worshiped in every way, He set His glory aside when He took on flesh and came and lived among us.  Though He deserved to be served and glorified for who He is, instead He came to serve and lived out His earthly ministry, not for His own glory but for the glory of Him who sent Him.

Paul tells us in Philippians 2:5-8,

Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men.  And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
