A famous Church of Christ argument has been that God told Noah to build an ark of gopher wood so that is the only wood he could use...not oak or pine...just gopher. Is that really true? Did the whole of human history revolve around Noah finding enough gopher trees?
Once you find out more about gopher wood you will see that the the whole argument falls apart. The argument that we can only use what is specifically and precisely biblical authorized falls on its face. It was already a pointless argument because no one only does the specific things mentioned in the Bible...no one.
