All Christians? Yes. All who claim to be Christians? No.<quoted text>
Jesus is telling Christians that He will send them to everlasting punishment for not taking care of the least of His brothers. Don't you believe ALL Christians are going to heaven no matter what?
What we believe is that (if) one is truely born anew , he is eternally secure and forever changed.
Shoud there be evidence of a changed life? I have said it for what seems like a thousand times. Yes. Does the evidence save you? NO. We are saved by faith. Nothing more.
