He who has realized love for God in his heart is tireless in his pursuit of the Lord his God, and bears every hardship, reproach and insult nobly, never thinking the least evil of anyone.
Those who seek the Lord should not look for Him outside themselves; on the contrary, they must seek Him within themselves through faith made manifest in action. For He is near you: 'The word is... in your mouth and in your heart, that is, the word of faith' (Rom. 10:8) - Christ being Himself the word that is sought.
A pure heart is perhaps one which has no natural propulsion towards anything in any manner whatsoever. When in its extreme simplicity such a heart has become like a writing-tablet beautifully smoothed and polished, God comes to dwell in it and writes there His own laws.
If the words of God are uttered merely as verbal expressions, and their message is not rooted in the virtuous way of life of those who utter them, they will not be heard. But if they are uttered through the practice of the commandments, their sound has such power that they dissolve the demons and dispose men eagerly to build their hearts into temples of God through making progress in works of righteousness.
