I realize it may be a silly point but I do not beleive it is a war against Christianity it is a war against Christ Himself. We knew or should have known it was going to happen, I think the surprise is that it is happening in our lifetime. We must be strong and fight the good fight. We are the Lord’s warriors.
I think that is characteristic of prophecy. We're told, we don't really understand, then when it is fulfilled we begin to think that it should have been obvious.
I think that when the Lord returns that will be the case.
I think that if we are in the end-times we're just now becoming suspicious that we will be surprised.
Anyway that was a good point.
How ironic, a war against Christ from those who don’t believe in Him. But the spirit behind it all knows that Jesus is Lord (and trembles).
