How do we know the doctrine of Jesus' humiliation is true?

The truth of Jesus' humiliation is firmly rooted in the prophetic scriptures of the Old Testament and the Gospel accounts. Isaiah 53 portrays the Messiah as one who is despised and rejected, foreshadowing the suffering He would endure. Additionally, accounts of His birth, life, and sacrificial death, as portrayed in the Gospels, affirm this doctrine. For example, Philippians 2:6-8 describes how Jesus, though in the form of God, took on human likeness and humbled Himself obediently to the point of death. Each of these scriptural references coalesce to confirm the reality of Jesus' humiliation, which is essential for understanding His mission to save His people from their sins.
