Humility

"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 made himself nothing, 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. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father."
Philippians 2: 5-11

Christ's humility consisted in his abasing himself from the highest pinnacle of glory to the lowest ignominy: our humility consists in refraining from exalting ourselves by a false estimation. He gave up his right: all that is required of us is, that we do not assume to ourselves more than we ought. Since, then, the Son of God descended from so great a height, how unreasonable that we, who are nothing, should be lifted up with pride!

"When a certain rhetorician was asked what was the chief rule in eloquence, he replied, 'Delivery'; what was the second rule, 'Delivery'; what was the third rule, 'Delivery'; so if you ask me concerning the precepts of the Christian religion, first, second and third, and always I would answer, 'Humility'
