There are many mega Churches today on the OSAS (once saved, always saved) doctrines of men. Many of them are prosperity ministries. Makes sense money would especially be involved, because those men are 'selling' Christ's salvation like the Roman Church tried to do with selling exemptions for the souls of member's dead relatives to get out of purgatory, which was one of the doctrines of men that upset Luther and caused him to declare his 95 thesis.
I like the way pastor Joe McGee described those in Christ. We may slip up seven times in one day, but we repent and ask Jesus forgiveness and then get back to working for Him. He well knows we can never be perfect in this flesh, and that we will slip up and sin at times. That is why He died on the cross for us, so as to be our Mediator to The Father for us, because while in this flesh, we are as filthy rags to God and but an unclean thing.
