How do we know the doctrine of Christ's ascension is true?

The doctrine of Christ's ascension is foundational to Christian faith, emphasizing that Jesus, after completing His redemptive work, ascended to heaven's throne. This truth is corroborated by several Scriptures, notably John 3:13, where Jesus states, 'No man hath ascended up to heaven, but he that came down from heaven.' The uniqueness of His nature as both God and man positions Him as the sole individual worthy of this ascension. Ephesians 1:20-21 further emphasizes His exalted state at the right hand of the Father, where He holds authority over all powers and principalities, confirming the truth of our Lord's ascension into glory.
