How do we know the ascension of Christ is true?

The ascension of Christ is documented in several places in the New Testament, notably in Mark 16:19 and Acts 1:9-11. These accounts are significant not only as historical events but as a fulfillment of Old Testament prophecy, such as that found in Psalm 47:5. The ascension serves as a divine affirmation of Jesus' identity and mission, reinforcing the truth of His resurrection and establishing His position at the right hand of God, where He intercedes for believers. This event is a critical aspect of Christ's mediatorial work, demonstrating His authority and power in governing His kingdom.
