This is one of my favorite verses:
And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full. But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who see what is done in secret, will reward you. And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words. Do not be like them,
for your Father knows what you need before you ask him.
This then, is how you should pray:
'Our Father in heaven, hallowed be your name...'
