>or you're wrong
I accept that I can be wrong all the time. Do you also accept that you could be wrong? Do you believe God can be wrong? Do you believe God can break a promise? o you believe that if God says a Moabite will NEVER enter into His congregation no matter how many generations go by, that He is lying? Can a Moabite be saved?

If a Moabite cannot be saved, then that answers your original question. No, we all cannot be saved through belief in Jesus.
