Matthew 6:16-21

“And whenever you are fasting, do not look gloomy like the hypocrites, for they put on a sad and dismal face [like actors, discoloring their faces with ashes or dirt] so that their fasting may be seen by men. I assure you and most solemnly say to you, they [already]have their reward in full. [Is 58:5] But when you fast, put oil on your head [as you normally would to groom your hair] and wash your face so that your fasting will not be noticed by people, but by your Father who is in secret; and your Father who sees [what is done]in secret will reward you. “Do not store up for yourselves [material]treasures on earth, where moth and rust destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in and steal; for where your treasure is, there your heart [your wishes, your desires; that on which your life centers] will be also.
