““Paul’s exhortation is in stark contrast to the “power of positive thinking” movement popularized by Dr. Norman Vincent Peale, which, in my view, was not altogether biblical because it seemed to suggest that people could change the future just by willing positive outcomes. Like the “prosperity gospel,” which tells us we can all be rich if we just have enough faith, it tends to detract from our proper emphasis on Christ-centeredness. There is nothing wrong with pursuing success and material blessings, but as Christians we must try to remember that our true contentment is embodied in Jesus Christ, and we should organize our lives around this truth.””
