St. Theodoros The Great Ascetic - 69 - 70

69. 'God does not want us to be lying idly on our backs; therefore He does not effect everything Himself. Nor does He want us to be boastful: therefore He did not give us everything. But having taken away from each of the two ahematives what is harmful. He has left us what is for our good.' Truly does the psalmist say: 'Unless the Lord builds the house, they labor in vain that build it; unless the Lord guards the city, the watchman keeps awake in vain' (Ps. 127:1). For it is impossible to tread on the asp and basilisk and trample on the lion and dragon' (Ps. 91:13. LXX), unless you have first cleansed yourself as far as you can, and have been strengthened by Him who said to the apostles: 'See, I have given you authority to tread on serpents and scorpions, and on all the enemy's power' (Luke 10:19). It is on this account that we have been commanded to entreat the Master not to 'lead us into temptation, but to deliver us from the evil one' (Matt. 6:13). For if we are not delivered from 'the fiery arrows of the evil one' (Eph. 6:16) through the power and help of Christ, and found worthy of attaining dispassion, we are laboring in vain, thinking that through our own powers or efforts we shall accomplish something. Therefore, he who wishes 'to stand against the wiles of the devil' (Eph. 6: I 1) and render them ineffectual, and to share in the divine glory, ought day and night to seek God's help and divine succor with tears and sighs, with insatiable longing and fire in his soul. He who wishes to share in this glory purges his soul of all worldly pleasures and of hostile passions and desires. It is of such souls that God Speaks when He says: 'I will dwell in them' (2 Cor. 6:16). And the Lord said to His disciples: 'if a man loves Me, he will keep My commandments: and My Father will love him, and We will come to him, and take up Our abode with him' (John 14:23).

70. One of the ancients spoke wisely and simply about thoughts. Judge thoughts, he said, before the judgment seat of the heart, to discern whether they are ours or those of our enemy. Place those which are good and properly our own in the inmost shrine of the soul, keeping them in this inviolable treasury. But chastise hostile thoughts with the whip of the intelligence and banish them, giving them no place, no abode within the bounds of your soul. Or, to speak more fittingly, slay them completely with the sword of prayer and divine meditation, so that when the robbers have been destroyed, their chief may take fright. For, so he says, a man who examines his thoughts strictly is one who also truly loves the commandments.
