What does the Bible say about the descent and ascent of Christ?

Ephesians 4:8-10 emphasizes the significance of Christ's descent and ascent. He came down from heaven, embodying God's humility as He condescended to save His people. This act was not merely a departure to the earthly realm; it was a condescension to the lowest state, akin to God becoming a mere worm for the sake of His creation. His ascent signifies the triumph over death and sin, where He led captivity captive and gave gifts to men, demonstrating His authority and victory over the powers of darkness.
