How do we know that Christ humbled Himself?

The humility of Christ is articulated in Philippians 2:7-8, which states, 'But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men.' This profound act of humility signifies that the eternal Son of God willingly chose to step down from His glorious position in heaven. It is crucial to recognize that this was not a loss of His divine nature, but an act of love and service towards humanity. Additionally, His obedience unto death, even the ignominious death of the cross, demonstrates the extreme depth of His humility and the gravity of His mission to redeem sinners.
