Joe is being a little dishonest. If I say “No, Christians and Muslims do not worship the same God.” … then that would suggest that Christians and Muslims worship DIFFERENT Gods.
Are there really multiple Gods?
No, there is only one God (supreme creator). So, when a Muslim or Hindu acknowledges a CREATOR (as Romans 1 suggests all men know), then they are worshiping “THE GOD” … there IS only one. However, the being described in the Quran is NOT the Jesus Christ of the New Testament who claimed to be that one GOD.
Therefore, it really is a YES and NO question that cannot be answered as Joe would have liked without giving a false answer. The Philosophers and Theologians that Joe quoted and mocked, all attempted to acknowledge that the being described in the Quran is not the Jesus Christ of the Bible, but there is only one God … not a God of Islam and a God of Christianity. (our God is not bigger than your God, God is the one and only God.)
