“What we should be most diligent about, I think, is this. First, we must continually ask God in our prayers to keep us in His hand, and bear constantly in mind that, if He leaves us, we shall at once be down in the depths , as indeed we shall… But most of all we must walk with special care and attention, and watch what progress we make in the virtues, and discover if, in any way, we are either improving or going back, especially in our love for each other and in our desire to be thought least of, and in ordinary things; for if we look to this, and beg the Lord to give us light, we shall at once discern whether we have gained or lost.”
– St. Teresa of Avila

“Oh, my sisters, how little one should think about resting, and how little one should care about honours, and how far one ought to be from wishing to be esteemed in the very least if the Lord makes His special abode in the soul. For if the soul is much with Him, as it is right it should be, it will very seldom think of itself: its whole thought will be concentrated upon finding ways to please Him and upon showing Him how it loves. This, my daughters, is the aim of prayer: this is the purpose of the Spiritual Marriage, of which are born good works and good works alone.”
– Teresa of Avila

“I saw my Guardian Angel, who ordered me to follow him. In a moment I was in a misty place full of fire in which there was a great crowd of suffering souls. They were praying fervently, but without effect for themselves; only we can come to their aid. The flames which were burning them do not touch me at all. My Guardian Angel did not leave me for an instant. I asked these souls what their greatest suffering was. They answered me in one voice that their greatest torment was long for God… [I heard an interior voice] which said, My mercy does not want this, but justice demands it.”
– Saint Maria Faustina

“Do not suppose, then, that when God brings a soul to such a point He lets it go so quickly out of His hand that the devil can recapture it without much labour. His majesty is so anxious for it not to be lost that He gives it a thousand interior warning of many kinds, and thus is cannot fail to perceive them. Let the conclusion of the whole matter be this. We must strive all the time to advance, and, if we are not advancing, we must cherish serious misgivings, as the devil is undoubtedly anxious to exercise his wiles upon us.”
– St. Teresa of Avila
