I feel sorry for the folks who believe this and then get so disappointed they abandon Christianity completely.
Exactly. For just about every group, it only takes a few loud people to give the entire group a bad name. Sad.
If they're so weak in the faith that they'd walk away over the failed prognostications of this charlatan, I'm pretty certain they never met the real Jesus in the first place.
Don't waste time praying for these deceived ones to come back to A Jesus they've never known; pray they'll come for the first time to the Real Thing.
Our God is a consuming fire, and His eyes are ablaze with fire; He is love — not that He fits into our definition of "love", rather His being defines what love is. Jesus is jealous for our very souls; he is bent on removing all that is in our lives that hinders our unrestrained love for Him. Our God is a warrior; He is actively destroying the works of evil, and we are the prize for which He fights. God loves us all so much that He came down here Himself and died to have fellowship with us. He delights in us; we are His joy and His song, and He is zealous for our reconciliation to Him. He WILL ultimately judge, condemn, and utterly annihilate all evil, but His fiery heart of love is toward us, wooing us to Himself, and whosoever will may come.
If that isn't the Jesus you know; you don't know Jesus. That certainly isn't the Jesus Camping talks about; I wonder whether Camping's followers would even recognize the Rider on the White Horse from Revelation 19:11 & ff.
