The preacher Has a point to make
He doesn’t have to prove it
Its up to the Holy Ghost , ‘ if the preacher is preaching in spirit and in truth.’
If however he is preaching in presumption, ‘then the preacher has a point to prove, and though he use the whole bible to do it, he can’t do it and wont get it done!’
But he will deceive himself and all those whom have the grave misfortune of hearing His speech!
