All of our holy fathers knew this and all with one accord teach that perfection in holiness can be achieved only through humility.

True knowledge is found only among those genuinely worshiping God.

We must, with God's help, eradicate the deadly poison of the demon of anger from the depths of our souls. So long as he dwells in our hearts and blinds the eyes of the heart with his somber disorders, we can neither discriminate what is for our good, nor achieve spiritual knowledge, nor fulfill our good intentions, nor participate in true life; and our intellect will remain impervious to the contemplation of the true, divine light; for it is written, 'Man's anger does not bring about the righteousness of God' (Jms. 1:20).

...we must first scrutinize thoroughly anything appearing in our hearts or any saying suggested to us. Has it come purified from the divine and heavenly fire of the Holy Spirit? Or does it lean toward Jewish superstition? Is its surface piety something which has come down from bloated worldly philosophy? We must examine this most carefully, doing as the apostle bids us: 'Do not believe in every spirit, but make sure to find out if spirits are from God'.

The thief who received the kingdom of heaven, though not as the reward of virtue, is a true witness to the fact that salvation is ours through the grace and mercy of God.

No structure of virtue can possibly be raised in our soul unless, first, the foundations of true humility are laid in our heart.

...we know that God arranges the opportunities for salvation in different ways. Our situation is that we respond eagerly or in a laggardly manner to these opportunities made available by God to us. God made the call come out of your homeland; Abraham by coming out was exercising obedience. There was the instruction come into the land; it was done, and that was the work of obedience. But the addition which I shall show you has to do with the grace of God, who gave a command - and a promise.
