I've heard a commentary saying that "taking the Lord's name in vain" refferes to oaths and promises and not necessarily to exclamations of surprise. I'm more simpathetic to this interpritation. It is said that for every vaid word we will give an account. I want to know, why should a vain word comprising of 3 consecutive letters G, O, D be worth of a greater sin then a vain word comprising of 4 consecutive letters H, E, C, K? What disguasts me is that I would meet people who would strangle you because you used "God" in a conversation, meanwhile that same person is divorsed 2 times (breaking the promise he made before God).
