But whenever you pray, enter into your inner room and shut your door [and] pray to your Father who is in secret, and your Father who sees in secret will reward you.

so that you will not be seen by people as fasting, but to your Father who is in secret, and your Father who sees in secret will reward you.

"Therefore do not be afraid of them, because nothing is hidden that will not be revealed, and nothing secret that will not become known.
