As Christians we are not called to be gullible and naive. We are commanded to test all that we are taught and hear. For what we believe affects the way we behave which has eternal consequences. The most important thing to believe is that Jesus Christ is the son of God who has come in the flesh. This is the theological plumb line for testing whether Prophets are speaking under the influence of the spirit of God or Satan. (1 John 4:1-6)
