The Third Commandment tells us to not take the name of God in vain – to not misuse his name. There are several ways that we can use God’s name in the wrong way, which we must not do:

First, we must not use his name in an oath and then not keep our oath (Leviticus 19:12). In our day that could apply to testifying in court or to our marriage vows before God.

Second, we must not use his name offering praise to him with our lips while our hearts are far from him (Isaiah 29:13). As we praise God’s name, our praise must be true – not just empty words.

Third, we must not put words in God’s mouth (Jeremiah 23:31). We ought not claim that God said something that he did not say. The other day I heard a local radio station tell us that “Jesus says” – and then go on to read from a bestselling book. But Jesus didn’t say those words, and so that is a misuse of his name.

Fourth, we must not use God’s name with contempt – speaking of God with scorn or ridicule or hatred.

Fifth, we must not use God’s name as a swear word. “Oh my God” should be reserved for our prayers, not as an empty utterance.

Sixth, we must not use God’s name in a flippant empty manner. For instance, when we say “God bless you” – do we mean it, or are we just throwing his name around?

Seventh, we must not use God’s name as a joke. Christians like to tell “Christian” jokes, but God must not be the punch line – God’s name is not a joking matter.

All of these ways that we misuse God’s name ought to make clear the positive requirement of the command. We must use God’s name with reverence and awe. He is a great and glorious God, and we must treat him as such. May God help us to honor his name.
