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

“Be [very]careful not to do your good deeds publicly, to be seen by men; otherwise you will have no reward [prepared and awaiting you] with your Father who is in heaven.

But when you give to the poor and do acts of kindness, do not let your left hand know what your right hand is doing [give in complete secrecy], so that your charitable acts will be done in secret; and your Father who sees [what is done] in secret will reward you.

But when you pray, go into your most private room, close the 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 pray, do not use meaningless repetition as the Gentiles do, for they think they will be heard because of their many words. [1 Kin 18:25-29] So do not be like them [praying as they do]; for your Father knows what you need before you ask Him.
