How do we know Jesus will return?

The certainty of Jesus' return is established throughout Scripture, particularly in the New Testament. As stated in Acts 1, the angel tells the disciples that the same Jesus who ascended into heaven will return in like manner. Additionally, 2 Thessalonians 1:7-10 reiterates this promise, describing Jesus' return with His mighty angels and the glory He will bring to His saints. This assurance is given to believers to strengthen their hope and prepare them for this inevitable event, encouraging them to live in anticipation of that day. The Scriptures serve as a reminder that while the timing is known only to the Father, the promise is sure.
