Calling it sound, solid, righteous, and great, he uses it to remove obedience to Christ.
As an example of the flattery and craft by which the devil draws the human will to cast off the good yoke of Christ, Saint Macarius the Great gives the following noetic warfare.
"Someone, quarreling with his brother, is troubled within himself and thinks: Shall I say this or that to him? No, I will not say it. He insults me so. Shall I speak against him?
"Better to be silent. True, we have the commandments of God, but one must also preserve one's honor. Thus it is difficult to deny oneself completely."
Therefore the Apostle commands decisive and complete self-denial. He commands us to put on the whole armor of God, not to gird ourselves with one weapon only.
Fasting alone is insufficient. Prayer alone is insufficient. Almsgiving alone is insufficient. Chastity alone is insufficient. The whole armor of God is all the commandments of the Gospel.
He who tramples one of them has trampled the whole assembly of them, the whole law. He who tramples one of them "shall be called least in the Kingdom of Heaven" (Mt 5:19), and will be sent into fiery Gehenna.
"I directed myself toward all Thy commandments; every way of unrighteousness I hated" (Ps 119:128). "Take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand" (Eph 6:13).
Only the one who has taken up all "the weapons of God" can "withstand in the evil day." Only the one who fulfills all the commandments without exception can stand against the enemy.
The "evil day" is the hour of fierce diabolical temptation and assault. Courageous warriors of Christ undergo it during their earthly pilgrimage, and through it the victors pass from eternal death to the resurrection of the soul.
For other Christians, the "evil day" is the day of the soul's separation from the body, the day of passage through the aerial toll-houses.
The saints of God clothed themselves in the whole armor of God. The rule of their life was the Gospel. Their word, the word of mouth, mind, and heart, was "the word of God" (Eph 6:17), the name of the Lord Jesus Christ.
With this spiritual sword they struck and crushed the revolving fiery weapon of the enemy. The words uttered by the devil and the fantasies depicted by him could not penetrate the soul, but were reflected from it in vain.
In the strictest watchfulness and sobriety, the servants of God attended to the mind and heart. Illumined by divine grace, from afar they already sensed noetic thieves and murderers approaching them.
In their attentive vigilance, as in a mirror, they saw the dark faces of the noetic Ethiopians. Having rejected communion with them here, they deprived them of every right over themselves.
After death, they passed unhindered by the aerial powers, whom they had trampled down in good time.
"Only the man who has truly renounced the world," says Saint Macarius, "who struggles, has cast off the earthly burden, freed himself, and sincerely withdrawn from vain desires, fleshly passions, authority, and human honors,
"who has secretly received help from the Lord in the hidden struggle, abides firmly in service to Him, and has finally surrendered his whole soul and body to the Lord,
"only such a man, I say, finds opposition, hidden passions, invisible snares, secret war, and inward battle.
"Standing in the midst of this warfare and praying unceasingly to God, he receives from heaven the spiritual weapons described by the blessed Apostle: the breastplate of righteousness, the helmet of salvation, the shield of faith, and the spiritual sword.
"Girded with these, he can withstand the hidden hostile devices directed against him.
"Having acquired these weapons through prayer, patience, supplication, fasting, and faith, he can wage war courageously against principalities, powers, and world-rulers.
"By conquering the opposing powers through the help of the Spirit and through his own virtues, he becomes worthy of eternal life."
When the devil sees someone unwilling to sin, he is not so senseless as to propose obvious evil to him. He does not say, "Go, commit fornication," or, "Go, steal."
He knows that we do not want this, and he does not labor to tell us what we do not want. Instead he tries to find in us some desire or some justification, and by these he harms us.
Therefore Scripture says: "The evil one does evil when he joins himself to the righteous" (Prov 11:15). The evil one is the devil. He does evil when he joins his righteousness to our righteousness.
Then he is strengthened, then he harms more, then he acts. When we are led by our own desires and follow our own righteousness, then, as though doing good, we lay snares for ourselves.
We do not even notice how we are perishing. This is from the instruction of Abba Dorotheus on not composing one's own understanding.
This is according to Blessed Theophylact of Bulgaria's interpretation. It is also clear from the lives of Saint Anthony the Great, Saint John the Much-Suffering of the Caves, and others.
