It is a hard thing to shift from enjoying the prosperity gospel, living it out and feeling that it works because you are well off - to changing your mind about it and discovering what the gospel is truly about. Why is it so difficult to see? Because its connected to a unique world view and an approach to understanding scripture that blocks the prosperity gospel adherent from seeing error.
Perhaps a starting point if you think you might be into prosperity is for you to listen to your favorite preacher and ask yourself the question: “Is this message fundamentally about me or is it about God?” Prosperity teaching will be man centred but biblically faithful preaching will be about God. The bible is God’s revelation about himself to us. Good teaching nd preaching will extend this and help us access biblical truth about God. Sure we learn stuff about ourselves along the way (eg, that we are wretched sinners) or how to walk the Christian walk, but at its essence - what is the preacher about?
"...I can't think of any other real purpose for which God has Christians on this planet other than to help bring his chosen ones into his kingdom through the proclamation of the gospel..." 
"...I have also been transformed in my thinking by the WOTM evangelism teaching and wholeheartedly recommend it to everyone. I enjoy sound doctrine and the occasional foray into apologetics." 
"...I have always desired to see people become Christians... I now know that I am being highly effective when I witness to friends and strangers because they are hearing the biblical gospel that can save them."

Thanks for that Dan! A very effective slap around the head - which we can all do with every now and then… even if we don’t subscribe to the prosperity doctrine described, most of us struggle with the root problem which is building our own kingdoms and seeking our own glory over God’s.
Awesome little message!
