Everything that breathes, breathes by air and cannot live without air; similarly all reasonable free creatures live by the Holy Spirit, as though by air, and cannot live without Him. "Every soul is quickened by the Holy Spirit." Recognise that the Holy Spirit stands in the same relation to your soul as air stands in relation to your body.

As the Holy Trinity, our God is One Being, although Three Persons, so, likewise, we ourselves must be one. As our God is indivisible, we also must be indivisible, as though we were one man, one mind, one will, one heart, one goodness, without the smallest admixture of malice - in a word, one pure love, as God is Love. That they may be one, even as We are One (John 17:22).

...if you wish to get pure air into your room, or if you go for a walk in the fresh air, think of the pure and of the unclean heart. Many of us like to have pure air in the room (and this is an excellent habit), or are fond of walking in the fresh air, but they do not even think of the necessity of the purity of the spirit or heart (of, so to say, spiritual air, the breath of life); and, living in the fresh air, they allow themselves to indulge in impure thoughts, impure movements of the heart, and even impurity of language, and most impure carnal actions.

How will it be with us in the future life, when everything that has gratified us in this world: riches, honors, food and drink, dress, beautifully furnished dwellings, and all attractive objects-how will it be, I say, when all these things leave us-when they will all seem to us a dream, and when works of faith and virtue, of abstinence, purity, meekness, humility, mercy, patience, obedience, and others will be required of us?

'With God all things are possible' (Mk. 10:27). With God the thought itself is deed. He speaks and it is. Short and clear. And all the worlds stand by the Word of God.

A man becomes spiritual insofar as he lives a spiritual life. He begins to see God in all things, to see His power and might in every manifestation. Always and everywhere he sees himself abiding in God and dependent on God for all things. But insofar as a man lives a bodily life, so much he does he do bodily things; He doesn't see God in anything, even in the the most wondrous manifestations of His Divine power. In all things he sees body, material, everywhere and always - "God is not before his eyes." (Ps. 35:2)

Christ wishes to raise men up to heaven, and has given them all the means to attain this; whilst the Devil, who himself for his pride was cast down from heaven into the dominions of the air, wishes by every means to attach men to earthly,- sensual, transitory things, and, in order to attain this end, he employs the most powerful, most prodigious means.
