Matthew 6:6-8

But when you pray, go to your room, close the door, and pray to your Father, who is unseen. And your Father, who sees what you do in private, will reward you. “When you pray, do not use a lot of meaningless words, as the pagans do, who think that their gods will hear them because their prayers are long. Do not be like them. Your Father already knows what you need before you ask him.
