There are several; occuring when the people turn away from Godl:
And with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. And for this reason God will send them strong delusion, that they should believe the lie, that they all may be condemned who did not believe the truth but had pleasure in unrighteousness. —2 Thessalonians 2:10-13And just as they did not see fit to acknowledge God any longer, God gave them over to a depraved mind, to do those things which are not proper. —Romans 1:28
But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons. —1 Timothy 4:1
Behold, the man who would not make God his refuge,
But trusted in the abundance of his riches
And was strong in his evil desire. —Psalm 52:7
Jesus told us to observe the signs of the times like others observed the weather.
Surely we are in the end times. There is a Very Strong Delusion prevailing in our ‘political leadership’ at this time.
