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.

He who devoutly strives to attain wisdom and is on his guard against the invisible powers, should pray that both natural discrimination - whose light is but limited - and the illuminating grace of the Spirit abide in him. The first by means of practice trains the flesh in virtue, the second illuminates the intellect so that it chooses above all else companionship with wisdom; and through wisdom it destroys the strongholds of evil and pulls down 'all the self-esteem that exalts itself against the knowledge of God' (II Cor. 10:5).

Unclean spirits increase the passions in us, making use of our negligence, and inciting them. But the angels decrease our passions, inciting us to the perfection of virtue.

Christianity is an entirely new way of being human.

He who is a beginner on the way must not be brought to practise the commandments by kindness alone, but must more often be induced to continue the struggle by being rigorously reminded of God's judgment. In this way he will not only be moved by love to desire what is divine, but will be moved by fear to avoid what is evil. For 'I will sing to Thee, O Lord, of mercy and judgment' (Ps. 101:1 LXX). He will sing to God charmed by love, and steeled by fear he will have strength for the song.

Trials are sent to some so as to take away past sins, to others so as to eradicate sins now being committed, and to yet others so as to forestall sins which may be committed in the future. These are distinct from the trials that arise in order to test men in the way that Job was tested.

... for our sake loosing within Himself the bonds of bodily birth, He granted us through spiritual birth, according to our own volition, power to become children of God instead of children of flesh and blood if we have faith in His Name (cf. Jn. 1:12-13). For the Savior the sequence was, first of all, incarnation and bodily birth for my sake; and so thereupon the birth in the Spirit through baptism, originally spurned by Adam, for the sake of my salvation and restoration by grace, or, to describe it even more vividly, my very remaking.
