THE OPENING OF THE GATES
The gates of Heaven are opened on Rosh HaShanah so the righteous
nation may enter (Isaiah [Yeshayahu] 26:2; Psalm [Tehillim]
118:19-20). Because the gates of Heaven are understood to be open on
Rosh HaShanah, this is further evidence that the rapture (natzal) of
the believers in the Messiah Yeshua will take place on Rosh HaShanah.
