Newcomers are "love-bombed" so that the newbie (often one who found it hard to fit in socially outside) thinks that it is great !
They have so much to learn, and it is so exciting...."It is like having God's battle plan for the end of The World" enthused one unbaptized publisher, to me once
There is a structure, an orderly routine of meetings and service to keep busy . Better than "Darning his socks in the night when there's nobody there " like Father Mckenzie in The Beatles "Eleonor Rigby"
Mainly they are bamboozled into thinking that this really is The Truth,that these people really do know all the answers . They do not have the knowledge, experience or critical thing skills to see it for what it is - so they lap it up..hook ,line and sinker.
