Some say that one’s faith is a private matter and should not be spoken of so publicly. (Source unknown)
People who say such things may not even have a concern for their faith in the privacy of their own lives. But there are probably a lot of sincere people who have a little religious persuasion but think it’s enough just to keep their thoughts to themselves. Unfortunately, such weak faith does little for the individual and absolutely nothing for others he or she may influence.
For I am not ashamed of this Good News about Christ. It is the power of God at work, saving everyone who believes (Romans 1:16).
