Matthew 6:6-7, 16-18

But whenever you pray, go into your innermost chamber and be alone with Father God, praying to him in secret. And your Father, who sees all you do, will reward you openly. When you pray, there is no need to repeat empty phrases, praying like the Gentiles do, for they expect God to hear them because of their many words.

“When you fast, don’t look gloomy and pretend to be spiritual. They want everyone to know they’re fasting, so they appear in public looking miserable and disheveled. Believe me, they’ve already received their reward. When you fast, don’t let it be obvious, but instead, wash your face and groom yourself and realize that your Father in the secret place is the one who is watching all that you do in secret and will continue to reward you.”
