The first suggests "You are a saint;' the other, 'You will not be saved.' Both come from the enemy, and there is no truth in them. Instead, think to yourself, 'I am a great sinner but the Lord is merciful. He loves man with a great love, and will forgive me my sins.' Believe in this way, and, you will see, the Lord will forgive you. But put no faith in feats of your own, however much you may have striven. An ascetic once said to me, 'I shall certainly be pardoned because I prostrate myself so many times a day;' but when death came, he rent his clothes.O how weak I am! I write a little and am already weary, and my body seeks rest. The Lord, too, when He was on earth in the flesh knew human weakness; and He, the Merciful One, grew weary on His way and slept in the boat during the storm; and when the disciples roused Him, He ordered the sea and the wind to be still, and there was a great calm. So, too, with us: great peace reigns in our souls when we call upon the holy name of the Lord. O Lord, grant us to praise Thee until our last breath!The Fathers of the Church say that the soul feels troubled and perplexed at visions proceeding from the enemy. But this applies only to the humble soul, who does not count herself worthy of visions, and feels either bewilderment or fear at the workings of the enemy; whereas the conceited man can experience neither fear nor even bewilderment, because he wants to have visions, and deems himself worthy of them, and so it is easy for the enemy to delude him. That which is of heaven is made known through the Holy Spirit, whereas earthly things are discovered by the mind — but the man who would discover God with his mind, through science and learning, is in a state of beguilement, for God is to be known only through the Holy Spirit. If in your mind you should think to see devils, humble yourself and try not to see them. Hasten to your confessor or the staretz to whom you have committed yourself. Tell him everything, and then the Lord will have mercy on you and you will escape delusion. But if you start thinking that you know more about the spiritual life than your spiritual father, and cease telling him in confession what befalls you, you will surely be beguiled for your pride. Fight the enemy with the weapon of humility.
