How do we know Jesus' return is true?

The truth of Jesus' return is substantiated by numerous biblical prophecies and the accounts of His ascension. The angels in Acts 1:9-11 confirm that He will return in the same manner as He ascended. Furthermore, Jesus' promises in the Gospels, such as in John 14:3 where He declares, 'I will come again, and receive you unto myself,' provide a foundational assurance to believers. The historical reliability of these accounts, coupled with their fulfillment in the past and ongoing hope in Christ's promises, reinforces the certainty of His return.
