Agape:
A church is a body of believers, rather than a denomination or building, as I'm sure you'll find even the Reasoning Book renders it. Hence your comment about what a church worships (I can only assume you mean a denomination here) is irrelevant. That you would propose an argument from a position of ignorance, pertaining to my religious practices, is a little worrying. How well do you think you know me?
Further:
It is a fact that most Religions worship Jesus as God.
Ermm, no. Actually its only the Christian religion that worships Jesus. Hindus, Muslims, JWs and a number of others do not.
When you follow the sequence of thoughts found in and around John 6:68 what do you find to be the focus of the Christian? Is it a denomination, a building or a person? I might further add "which person?", but suspect that might be a little too difficult for you to grasp at this juncture.
Confession:You have it summed up pretty well. Most folks dont leave the JWs and start attending, but then neither do the general population attend church. I think the proportion is likely comparable.
Moomanchu:Some smell of incense.
