Everything is possible for the believer. I have watched impure souls mad for physical love but turning what they know of such love into a reason for penance and transferring that same capacity for love to the Lord. I have watched them master fear so as to drive themselves unsparingly toward the love of God. That is why, when talking of that chaste harlot, the Lord does not say, 'because she feared,' but rather, 'because she loved much' she was able to drive out love with love (Lk. 7:47).
John ClimacusWhen you are depressed, bear in mind the Lord's command to Peter to forgive a sinner seventy times seven (cf. Mt. 18:22). And you may be sure that He Who gave this command to another will Himself do very much more.
John ClimacusWhoever has become a servant of the Lord fears only his Master. But whoever is without the fear of God is often afraid of his own shadow. Fearfulness is the daughter of unbelief. A proud soul is the slave of fear; hoping in itself, in comes to such a state that it is startled by a small noise, and is afraid of the dark.
