All nations, right?
You've mentioned the Tower of Babel before, but you ignored me when I mentioned Pentecost as the recapitulation of Babel. The Gospel has the power to remove the things that would divide us, including race. So whether the majority is comprised of gay, baby-killing whites, or gangbanger blacks, they must be evangelized all the same.
Yes, all nations, meaning in their separate homelands and spread the word to them.
If you think jamming everyone together under the same system, is Christian in nature, or would ever work, you are very mistaken. And that is the reason groups like PF are growing very quickly.
