A listener fears that BEL advocates that the government largely adopt the Bible's Mosaic Law, and so Bob talks him through the principles by which we "rightly divide the Word of Truth" (2 Tim. 2:15), distinguishing between specific laws for Israel, and general laws for all governments, including the difference between symbolic and moral laws.
Iowa Caller: David tried to refute the talk show host as Bob argued that God does NOT want governments to enforce Israel's symbolic Sabbath law, and that God required the death penalty for those under Israel's covenant who worked on Saturday. "...Whoever does any work on the Sabbath day, he shall surely be put to death. Therefore the children of Israel shall keep the Sabbath... It is a sign...' -God Exodus 31:15-17
