Christ’s path to being lifted up (quite literally on the cross and from the grave) was through the means of being made less—taking on the form of a servant, becoming human, and humbling himself by becoming obedient to death by crucifixion.
Likewise, our glorification necessitates we experience humiliation. The story of our freedom and salvation is not the story of our strength or greatness. It is the story of grace; a free and unmerited gift. Therefore, if it is not by our strength or merit then we have no control over it. Pride and ego thus experience humiliation. If it is not by our by force or might, but through a crucified God, then human wisdom experiences humiliation.
“The way to Christ is first through humility, second through humility, and third through humility. If humility does not precede and accompany and follow every good work we do, if it is not before us to focus on, it it is not beside us to lean upon, if it is not behind us to fence us in, pride will wrench from our hand any good deed we do at the very moment we do it.” St. Augustine
“The stone rejected by the builders is now the main foundation stone!” Psalm 118:22
“The message of the cross is foolishness to those who are being destroyed. But it is the power of God for those of us who are being saved.” 1 Corinthians 1:18
