It may be easily understood that it would suit the devil's cause very well indeed if we can be deceived and deluded with regards God's will. After all, that was the essence of the very first temptation. We are told that the serpent beguiled Eve through his craftiness. It was Paul's concern that the Corinthians might not be likewise beguiled, 2 Corinthians 11:3.

I believe that there is no area of Bible knowledge today about which God's people are more confused and deluded than that of the end times.
