Are you done yet ..??
Hmmmm? For such a response, I must have challenged your theology. Frankly, I don't give a rip if I did. I don't see anybody twisting your arm forcing you to believe what I said. You are perfectly free to believe whatever you want.
And .. YOU ARE WRONG - there are 3 groups. The Jews are God's chosen - and He deals with them separately. The other 2 groups are the believers and the non-believers .. or the church and the nations.
And .. as far as Isaiah goes .. HE WAS PROPHESYING - after all, he was called a prophet.
By the way .. discussing what you believe is not a contest. It's an opportunity to share what you believe. If I don't believe the way you do - that's fine with me and it should be fine with you. But .. if you REQUIRE me to believe the way you do .. I guess our conversation will end.
