How do we know Christ's humiliation and exaltation are true?

The doctrines of Christ's humiliation and exaltation are rooted in the Scriptures, particularly in Philippians 2:5-11, which lays out the sequence of His humble incarnation, obedience unto death, and subsequent exaltation. The biblical narrative presents both His condescension, as shown in His birth and earthly ministry, and His glorification through resurrection and ascension. These events were predicted in the Old Testament and fulfilled in the New Testament, affirming their divine truth. Moreover, the witness of the apostles and the consistent testimony of the early church further validate these doctrines as essential tenets of the Christian faith.
