Yes I do, however my family & I say "Thank you, Lord!" because we don't want to offend Him or break the 2nd commandment. Also because the rest of the world says God's name so flippantly, if we were to say, "Thank God" it would be assumed we were misusing His name which would also offend Him & break the 2nd commandment, if only by proxy. That's why we're careful not to use God's name except in explanation or prayer. We love God & won't exchange Him for anything, not a movie, tv show, or book. I get that you have the characters being grateful to the Lord, I really like that, if you could still edit it though & rewrite it to be "Thank you God"? That comes out more like they are talking to God, not misusing His name, at least it does to me, you know, one author to another. Thank you & God Bless.
