Commenting on the Gospel for Ash Wednesday, (Matthew 6:16-22) Saint Augustine writes: "From
these precepts it is evident that our every action should be directed
towards the attainment of an interior life, which alone giveth true
happiness. For if contrariwise we seek our reward in outward things,
we shall be conformed to the fashion of this world, and thus forfeit
God's promise of happiness, to wit, that we shall be conformed to the
image of his Son. Such happiness, inasmuch as it concerneth inward
things, is all the more certain and enduring." Indeed Lent is the time to establish or improve our interior life. We should be abstaining from worldly things in order to spend more time in spiritual things.
