Let's see, first you are told you are under satan's control, a sinner, with no hope for the future. Hmm, sounds like the tearing down phase to me.
Then you see the "truth" bit by bit and are praised for your maturity and insight. Hmm, sounds like the building up phase to me.
Then you find you are in an elite corps of faithful witnesses who alone have God's blessing. Hmm, sounds like you feel better than everyone else thanks to the WBTS.
Drop and give me twenty maggot!
