It would be interesting to see the statistics on
% of infidelity among the public at large vs % infidelity among pastors of mega churches. I think the % would be disappointing.
I think one can be a committed, Bible believing, God fearing, evangelical Christian and question the feel good doctrine coming out of the mega churches and which dominates televangelism; about how simply turning all your problems over to God will result in financial and marital success.
I expect that it's very much higher.... Certainly the temptation and opportunities are greater than most folks will experience.
It's why St. James cautioned us, Not many of you should become teachers, my brothers, for you know that we who teach will be judged with greater strictness. For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body. (James 3:1-2)
I think mega-church founders tend to have a sort of narcissism about them -- it's not necessarily all bad, but it perhaps makes them more prone than most to be tempted.
