You shall not misuse the name of the LORD your God, for the LORD will not hold anyone guiltless who misuses his name. – Exodus 20:7
This verse always disturbs me because I worry about using God's name in vain by accident. That OMG that is frequently used in email or text, I write OM goodness. I don't say "jesuschrist" or GAWD. I also don't say YAHWEH. I read today concerning this verse that it is more about not using his name to guarantee our own things that would not exhalt God. for example, if I said, I swear by God that I will do something (that I never intend to do) in order to fool the person into believing me. That is holding God as a false witness. Or to swear an Oath by God and then lie. Or, believe me, I'm a Christian, extorting our following of Christ. That makes better sense to me. In the Bible, God said his name is I AM that I AM. We don't going around saying that. I don't pray to I AM. I know him as God. Father, Lord. It is good to pay attention to how I know him.
