Matthew 6:6-8

6But when you pray, go into your inner room, shut your door, and pray to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.

7And when you pray, do not babble on like pagans, for they think that by their many words they will be heard. 8Do not be like them, for your Father knows what you need before you ask Him.
