"The kingdom of
heaven is like unto leaven, which a woman took, and hid in three measures of
meal, till the whole was leavened" (Mt. ).
The "three measures of meal" symbolize
the three powers of the soul transfigured by God's grace: mind, will and
feelings. Grace enlightens the mind, opening new spiritual truths before it; it
strengthens the will in good works, and appeases and cleanses the feelings,
implanting light joy into the man. Nothing in the world is comparable to the
grace of God: the earthly things feed and strengthen the temporal body, but the
grace of God feeds and strengthens the immortal human soul. That is why a human
must first of all value the grace of God and be able to sacrifice everything
else for the sake of this grace, as our Lord said in His next parable.
