I often hear pastors add "in Jesus name" at the end of their prayers before the Amen. I understand the reasoning for this comes from John 14:13-14, John 15;16 and John 16:23 where Jesus tells the disciples to ask for anything in His name and it will be done. I have two questions about this. 1. Does this apply to all, or just the disciples and 2. Isn't the Amen at the end of our prayers supposed to be the same thing, considering that Jesus is the "Great Amen"?
