In the Old Testament, a prophet who falsely attributed words to the Lord could face the death penalty. There are also numerous scriptures that warn against adding to God's word. Here is an example, Proverbs 30 5 “Every word of God is flawless; he is a shield to those who take refuge in him. 6 Do not add to his words, or he will rebuke you and prove you a liar. (NIV) The Bible also warns against coarse jesting and blasphemy. Why am I saying this? We have to have some limits to our humor, especially when it pertains to the Almighty. We shouldn't make jokes about God being deceptive or unfaithful to His promises. We shouldn't make jokes where we put words in God's mouth that He did not say.
