What does Revelation 22:16 mean?

Jesus had sent His angel to deliver the message of Revelation to the apostle John. He said the message of Revelation is "for the churches." Presumably, churches should be teaching and heeding the contents of this last book of the Bible. To ignore the book of Revelation is tantamount to rejecting the gift Jesus has presented to the churches.

This verse also tells us Jesus is "the root and the descendant of David" and "the bright morning star." Jesus was born as a descendant of King David (Matthew 1:1, 6–16) He is the rightful heir to the kingdom God promised to David (2 Samuel 7:12–16). The angel Gabriel prophesied that Jesus would reign over His kingdom from the throne of His father David (Luke 1:31–33). But Jesus is also "the bright morning star." Malachi 4:2 promises Israel that the sun of righteousness will arise with healing in its wings. Revelation 22:16 identifies Jesus as "the bright morning star." Just as the morning star appears before the sun rises, so Jesus will come for the church before he returns to restore Israel to himself.
