"I have no problem calling Jesus my Lord and my God, in the qualified sense in which the Bible presents him as a divine being. But Thomas may not have addressed Jesus as such (see my book for details). You are the one who has the problem, for neither Thomas nor any other Bible personage uses the term "God" in a manner consistent with trinitarianism. Yet, you and others appeal to these verses as if they support your theology!"
(Arian, former Jehovah's Witness Greg Stafford, in debate with trinitarian Rob Bowman)

Romans 10:9-13 because, if you confess with your lips that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
