There was an interesting show on Nightline last night titled, “Does Satan Exist?” You can link to it here: http://abcnews.go.com/nightline/faceoff
This is all I have to say: I challenge anyone. Pursue a walk with the Lord, seek God with all your heart, mind and soul. Believe me, you will find out that Satan DOES indeed exist. But not to worry! Jesus is faithful!
“The Lord is faithful, who will establish you and guard you from the evil one.”2-Thessalonians 3:3
