I find this question most interesting and how it relates to a current situation that is taking place in the County I live in. We have a local church that has been very outspoken and strongly opposed to the building of an Islamic Mosque in the same township that they recently built their new church. The Senior Pastor states that those people don't worship the same God as we worship. Unless something has changed Jews, Christians and Muslims all worship the same God just in different methods. This attitude goes against every aspect of the message that Jesus was addressing in this question.
