If Heaven only has 12 gates with the names of the 12 tribes and only they can enter, what gate do the gentile think they will enter?

read Revelation 21:27," those who's names are written in the Lambs book of life shall enter unto salvation".

Colossians 3:11 

 ‭Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond ‭nor‭ free: but Christ ‭is‭ all, and in all.‭ 

Heaven doesn't have "gates", or anything else physical. It is a spiritual state of existence, not a physical place. What you are referring to was simply a symbolic vision given to a specific individual.

Blind reading of the texts by those not in the faith is valueless 

All of them.  'cause we're takin' over in a one night brawl-for-all.

I can't imagine worrying about stuff like that...

But there were more tribes, Ephriam, Manasseh, Joseph.  Rev. 7:6, 8.  Where are the other gates?

The Big Pearly One with ST. Peter and the Big Book of sinners and saints.  I saw it in a movie once.

The one with a toll. I'm hoping they'll take cash. I don't have EZ Pass.

Everyone should be grafted in one of those tribes .
