We don't necessarily disagree. Tithing is only a very small part of Biblical stewardship. Yes, Dave does mention tithing, but it is in the context of factual information in order to promote Zander and his ELP agenda.
I don't feel any push towards the "Zander" or "ELP" agenda. I listen to his show frequently and understand that Zander is a paid advertiser. He rarely even mentions the ELP's and when he does he just says go to his website to find one. ELP's don't pay him, they just get screened by him.
I agree with most of Dave's teachings. The biggest thing is the "get rid of debt" part. I paid of my house at age 45 and it's a great feeling. The amount of money you save by not having interest charges on homes/cars/retail etc is HUGE.
