That is up to you. I would wonder just how committed to core Christian values a pastor is who drives a 2005 Mercedes. He doesn't have to drive a heap - but, last I checked, Christ called upon his servants to eschew such trappings.
And I don't care if it is Benny Hinn or a stockbroker - if they don't provide an accounting of what happens to money entrusted to them, you shouldn't give them money. It's that simple.
I don't give Benny Hinn any money I do give other organizations money who ask for it.
I am curious to know something People for the most part who are not believers of Jesus Christ which would include:
(Meaning they don't believe he is The Son of GOD the Saviour of MAnkind)
Muslims, Hindus, Jews, Atheists,Buddhits, how would you introduce them to Jesus his word, his ministry his salvation? ANd they do not beleive the Holy Sciptures so how can you make a un-believer a believer?
