The enemy of our salvation especially strives to draw our heart and mind away from God when we are about to serve Him, and endeavors to adulterously attach our heart to something irrelevant. Be always, every moment, with God, especially when you pray to Him. If you are inconstant, you will fall away from life, and will cast yourself into sorrow and straitness.
So long as the soul is sick with passions, its senses have no perception of the spiritual; and the soul does not even know how to desire it, but desires it only from hearsay and writings. The power of the soul is cured of these diseases by the hidden practice of commandments, with sharing in Christ's passion.
If we cut off the causes of the passions for only a short while, and occupy ourselves with spiritual contemplation without making it our sole and constant concern, we easily revert to the passions of the flesh, gaining nothing from our labor but theoretical knowledge coupled with conceit. The result is a gradual darkening of this knowledge itself and a complete turning of the intellect towards material things.
If Nabuzardan, the court cook of the King of the Babylonians, had not gone to Jerusalem, then the Temple would not have burned (cf. 2 Kings 24), That is to say, a person’s mind is not attacked by the flames of carnal pleasures, if a person is not conquered by gluttony.
If the passions strike you from time to time, this should not distress you. We must continue the 'unseen warfare' all our lives. The battle itself is not a problem; there is trouble only if we become weak in it. If this does not happen, our spiritual life is in good order. The peace that is with you in battle bears witness to this. But we must beware that we do not feel a different kind of peace, the kind one feels when there is no battle. This kind of peace is dangerous. It indicates that the enemy has done away with open battle and wants to build an invisible and clever snare for us! In cases like this one must intensify one's usual vigilance and sobriety! Do not weaken in any way!
The roof of any house stands upon the foundations and the rest of the structure. The foundations themselves are laid in order to carry the roof. This is both useful and necessary, for the roof cannot stand without the foundations and the foundations are absolutely useless without the roof-- no help to any living creature. In the same way the grace of God is preserved by the practice of the commandments, and the observance of these commandments is laid down like foundations through the gift of God. The grace of the Spirit cannot remain with us without the practice of the commandments, but the practice of the commandments is of no help or advantage to us without the grace of God.
One must clean the royal house from every impurity and adorn it with every beauty, then the king may enter into it. In a similar way one must cleanse the earth of the heart and uproot the weeds of sin and the passionate deeds and soften it with sorrows and the narrow way of life, sow in it the seed of virtue, water it with lamentation and tears, and only then does the fruit of dispassion and eternal life grow. For the Holy Spirit does not dwell in a man until he has been cleansed from passions of the soul and body. Only one thing may remain within a man, either the Holy Spirit or the passions. Where the Holy Spirit is, there the passions do not come near, and where the passions are, there the Holy Spirit does not dwell, but rather the evil one.
