In my opinion, Barack Hussein Obama is as evil as any human that has ever walked the face of the earth.
What is extremely disturbing is that so few are unable to discern that there is even a little bit wrong with him.
Truly. I really believe that satan himself, at least part of the time, inhabits him. If one has spiritual discernment you can discern satan in him at times.
The Bible makes it clear why God is sending a strong delusion in the end times: They perish because they refused to love the truth and so be saved. For this reason God sends them a powerful delusion so that they will believe the lie and so that all will be condemned who have not believed the truth but have delighted in wickedness (2 Thessalonians 2:10-12).
Simply put, God sends a strong delusion to those who chose not to believe the gospel of Christ. Those who take delight in mocking and rejecting Him, He will condemn.
