I like rhetorical questioning. It provokes thought in a manner not otherwise so acceptable. In that vein, it occurred to me to addresses Biblical issues in the following manner.
If the bible is true, then……
One may enter any scriptural principle following the “then” to make one’s point.
For instance, if the bible is true giving away something every day should result in one’s prosperity since a generous man will prosper.
If the bible is true, then one who is careful to do what is commanded (not suggested) therein will prosper in all that they put their hand to.
I found the rhetorical question route to discussion of what otherwise may not be palatable very appealing, especially if the bible is true.
