I've listened to maybe 10-15 of his audio's on youtube and all of them are consistent personality wise. I really do not think he cares about the money. I assume his retirement as a firefighter covers his expenses well enough. He does want the information in the book to get out and for it to stir people to pray as well as give the church universal hope and encouragement.
One of the reasons I feel he is congruent is his descriptions of how he received a message from The Lord. It is consistent with my own experiences and those of many people I know.
He's very matter-of-fact. And most of the stuff he receives from God comes unbidden when his mind is on something else quite different from the content he receives. Sometimes he receives an answer to something he is prayerfully pondering or asking God about at that moment.
I'd be interested in your assessment after you listened to 5-8 of his youtube dialogues.
Send me what you think I should watch or listen too in the freepmailbox. I will let you know what I think. Cheers! Heading of to dream land town shortly.
