The go-to passage for prayer groups and prayer meetings across the globe is Jesus’ words in Matthew 8:19-20:
Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. 20 For where two or three are gathered in my name, there am I among them.”
The common interpretation of this passage is that Jesus is present when two or three believers have gathered and agree together in prayer concerning any matter. Even when I subscribed to this interpretation, I always had the nagging question about the implications this had for praying alone. Is God not present when you are praying by yourself? I resolved that perhaps God was present in a special way when more people were gathered. The power of unity, right?
