7 Thou shalt not take the name of the Lord thy God in vain; for the Lord will not hold him guiltless that taketh his name in vain.

Here we have the third commandment, not to take the name of the Lord in vain. When I was a child, I was told this meant not to use religious profanity. For example, spitting out the name of “Jesus Christ” to express anger or shock. And while I still do believe it is particularly wrong to curse in ways that desecrate the divine, I don’t believe that this is the practice specifically being called out in this verse.

The “taking of the name of the Lord,” calls to mind how Christians “take upon themselves the name of Christ.” Taking the Lord’s name means taking His covenant, calling yourself one of His people, declaring your intention to live as He would have you do.

And that should most definitely not be a commitment made in vain. It is to be a most serious promise. If you are making the commitment to follow Christ lightheartedly, or abandoning him soon thereafter, or trying to twist his words to match your preferences, then you are taking his name in vain. You are saying that you are a follower of the Lord, when you’re really not at all.

Sadly, in our Western civilization where most of us were born under the umbrella of Christianity, I believe that “taking of his name in vain” is one of our most common sins. We take our status as “Christians” for granted, assuming that since we were born with that title it belongs to us no matter what we say, think, or do. Our lighthearted approach to our faith cheapens the name of Christendom to the rest of the world, and makes a mockery of our God. The message from God in today’s verse is, “if you’re going to take my name, mean it!”
