Matthew 6:1, 3-4, 6-8

“Beware of practicing your righteousness before men to be noticed by them; otherwise you have no reward with your Father who is in heaven.

But when you give to the poor, do not let your left hand know what your right hand is doing, so that your giving will be in secret; and your Father who sees what is done in secret will reward you.

But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you. “And when you are praying, do not use meaningless repetition as the Gentiles do, for they suppose that they will be heard for their many words. So do not be like them; for your Father knows what you need before you ask Him.
