Matthew 6:6 Praying Alone.
But when you pray, go into your room, close the door and pray
to your Father, who is unseen. Then your Father, who sees what is done in secret, will
reward you.
Matthew
18: 19-20 Praying Together
Jesus said "Again, I tell you that if two of you on
earth agree about anything you ask for, it will be done for you by my Father in heaven.
For where two or three come together in my name, there am I with them."
