From a netfriend:

[A lecturer at a pastors' conference] does a confronting demonstration of the effect of extra- and pre-marital sex on a marriage. He calls a couple out to the front to be the pair about to be married. Then we are told that each has had previous partners. Others are called out to line up beside them, holding hands, to represent these sexual partners. Of course, some of these have also had partners, and so on.

Once there is a line of people right across the stage we are told that one of the women is into witchcraft, one man is an active satanist, others are under freemasonry curses, some are homosexual, etc. And they are all spiritually joined! The greatest shock for some was to realise that for the man in the centre, the person on the other side of his wife to be is usually another man. They are spiritually joined, and if this linkage is not broken, then there exists a homosexual relationship between these two men. This applies also to the wife. The witch may have occult access to the marriage bed. Any demons in the group could possibly be shared by the others. Need I go on?
