Don’t practice righteousness to be seen.
‌When you give don’t announce it with trumpets.
When you pray don’t stand on the street corners.
When you fast don’t disfigure your faces.

Hypocrite (properly an actor)
one who outwardly plays the part of a religious man to perfection,
but is inwardly alien to the spirit of true religion.

Jesus is calling us to a real and genuine faith.
