Would it be alright if I was to say "Thank God?" I'm not sure, as I'm quite a new Christian. This is the context:
I am late for the plane. I rush through the check-ins and stuff, and I reach the plane just in time. I say, "Thank God!".
Would that be counted as using God's name in vain? This comes from this question.
What about saying "Thank the Lord!" Would that be taking the Lord's name in vain?
