Sadly it is getting harder to separate out the truth that the Lord does want to meet our needs and yes, even 'prosper' us from the teachings of TV ministers that are preaching wealth. Prosperity is revealed in the bible to include peace, wholeness etc

When I have seen documentaries exposing Benny Hinn's lavish lifestyle I have been offended because he is missing the obvious

2 Cor 9:8
And God is able to make all grace abound toward you, that you, always having all sufficiency in all things, may have an abundance for every good work.
(NKJ)

Benny and others have missed the fact that the abundance God has given them is for EVERY GOOD WORK and not for themselves. The 'all sufficiency' is for them (bills met, perhaps?).

They are stealing if they have kept the abundance for themselves.
