Adoption: should Produce an Avoidance of Ostentation

“Be careful not to perform your righteous acts before men to be seen by them. If you do, you will have no reward from your Father in heaven. …

But when you pray, go into your inner room, shut your door, and pray to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.

…so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.
