Be not deceived; the mainstream churches will not take kindly to our characterization of them. They aren’t evil in the sense of knowingly perverse, but that doesn’t mean they aren’t following a perversion of the gospel message. The vast majority of mainstream Western Christians are deceived, and it is a divine mercy that we do what we can to get their attention. It is the leadership where we are likely to find some who recognize that, in our refusal to build little kingdoms for ourselves, we are the greatest threat to their little kingdoms.
Walk by the Spirit — whatever else that means, it requires that we shift the focus of our awareness to the heart-mind.
The matter of “doing God’s will” is not a long list of rules and principles. The actions and their results are mere manifestations, not the thing itself. His will starts with operating from the heart-mind. His will is, by definition, embracing the image of His revealed character as the moral fabric of the universe. It requires exercising a non-intellectual faculty that the Bible calls “faith,” itself just a word that means commitment to live by our convictions.
