One of the most obvious ways of taking the Lord's name in vain is through profanity. Unfortunately, most of us have heard the Lord's name taken in vain in that sense. That always bothers me, because that is my Lord they are speaking of. We might even find ourselves correcting someone. "You shouldn't take the Lord's name in vain," we might say. And right we are.
Jesus said, "But why do you call Me 'Lord, Lord,' and not do the things which I say?" (Luke 6:46). When we say that He's our Lord, yet we don't do what He tells us to, that is the ultimate way of taking His name in vain. Hypocrisy in the church is far worse than profanity in the street. Let's be careful not to take His name in vain.
