For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
~ Romans 1:26-27
And for this cause God shall send them strong delusion, that they should believe a lie:
That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
~ 2nd Thessalonians 2:11-12
Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
~ 2nd Thessalonians 2:3
And, of course, these scriptures are mightily reinforced by Old Testament ones, too...
You are so right in posting those scriptures. We are being forced to choose and declare our allegiances. Anyone who is not totally dedicated to the truth of God and a personal relationship with Him be forced to show themselves. On the other hand, those who have a personal relationship will need to remain strong and increase their dedication to Him. The wheat and chaff are being separated.
