In prepping for this coming Lord’s Day sermon I’ve been studying Philippians 1:27-30 and John MacArthur shares this insight on Paul’s sense of fear and really lack thereof when it comes to fear of things in this world:
Paul was not afraid of ridicule, hardship, suffering, or death. His convictions were firm and unwavering, so that he did not compromises divine truth. On such matters he was unshakable. His one fear was that he would be disqualified from ministry. No matter how sound his doctrine remained, Paul understood that the danger of disqualification stemmed in large measure from the misuse of his body. He therefore declared his determination to “discipline his body and make it his slave” (1 Cor. 9:27). The primary, if not the sole, misuse of his body he had in mind was sexual immorality. – from MacArthur New Testament Commentary: Philippians p. 87.
Orthodoxy with out orthopraxy is an ugly and dangerous thing. God help us to, “only conduct ourselves in a manner worthy of the gospel of Christ.”
