What argument did Les's Muslim listener make against Jesus being God?
A Muslim listener argued that Jesus was never God, but merely another prophet. He claimed Muhammad superseded Jesus because Muhammad came on the scene later. The listener raised this as one of several arguments in a letter after watching the program.
Les explains that he received a letter from a Muslim listener who had been watching the program. The man began his letter as a Muslim and presented many arguments. One argument was that Jesus was never God; instead, he said Jesus was just another prophet, and that Muhammad had now superseded Him because Muhammad came on the scene later. Les uses this to emphasize that many believers are unaware of who Jesus really is, namely the Creator God, the same God who created everything in Genesis chapter 1 and the Christ of the cross.
