Matthew 6:6-7, 16-18

But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you. “And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words.

“And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you.
