“The apostle Paul was consistent. Paul desired “that whenever I open my mouth, words may be given me so that I will fearlessly make known the mystery of the gospel” (Ephesians 6:19). When he said hard things he was able to remind those who knew him how consistent his life was with the gospel (Acts 20:18; 2 Timothy 3:10). So make sure the message you share is consistent with the message you bear. Endeavor, by God’s grace, to think through how to keep careful watch over your life as well as your doctrine by living out the gospel.”
