He humbled himself, becoming obedient to death, even death on a cross

The life God gives is not all at once, but moment by moment, through the unceasing operation of His mighty power. Humility, the place of entire dependence on God, is the first duty of the creature, and the root of every good quality. 

Likewise, pride, or the loss of this humility, is the root of every sin and evil. It was when the Serpent breathed the poison of his pride – the desire to be as God – into the hearts of Adam and Eve, that they fell from their high position into all the wretchedness in which mankind is now sunk. In heaven and earth, pride is the gate, the birth, and the curse of hell.

Therefore, it is reasonable to say that nothing can be our redemption except the restoration of the lost humility, the original and only true relationship of the creature to its God. So Jesus came to bring humility back to earth, to make us sharers in it, and by it, to save us. In heaven, He humbled Himself to become man. The humility we see in Him possessed Him in heaven; it brought Him, and He brought it, from there. Here on earth, he humbled himself and became obedient unto death (Philippians 2:8). His humility gave His death its value, and became our redemption. Now, the salvation He makes known is nothing less and nothing else than a communication of His own life and death, His own nature and attitude, His own humility, as the ground and root of His relationship to God and His redeeming work. Jesus Christ took the place and fulfilled the destiny of man, as a creature, by His life of perfect humility. His humility is our salvation. His salvation is our humility.

ISAIAH 55 

6   Seek the LORD while he may be found,  call upon him while he is near.     

7 Let the wicked forsake their way, and sinners their thoughts; Let them turn to the LORD to find mercy;    to our God, who is generous in forgiving.     

8 For my thoughts are not your thoughts, nor are your ways my ways — oracle of the LORD.    

9 For as the heavens are higher than the earth,  so are my ways higher than your ways, my thoughts higher than your thoughts.
