The following verses indicate the SON OF DAVID, MESSIAH will reign forever:
Isaiah 9:6-7
2Sam 7:16
Psalm 89:35-37
Heb 1:8
2 Peter 1:11
Luke 1:32-33
These are just a sample of verses indicating quite clearly that Messiah will continue as King forever. They specifically reference THE SON being KING for EVER.
Now, which verses tell us that Jesus will in some way CEASE to reign? Or that the Son will cease to reign? Or that the Son"ship" will cease?
