Today's main reference is Jas 2:26.
What should we believe and what actions should we have? Does a person have real faith just by claiming to believe in Jesus? Does a person have proper actions just by acting according to his or her own thoughts?
In fact, the Bible contains the promises we must believe and upon which we must act (Acts 2:14-26). The faith that was necessary at the time of the first coming was to see and believe that Jesus fulfilled the Old Testament. The faith necessary at the time of the second coming, therefore, is to see and believe in the fulfillment of the New Testament when it is fulfilled (Jn 14:29). What, then, are the actions we must have?
