We cannot be sure if we are loving God, although we may have good reasons for believing that we are, but we can know quite well if we are loving our neighbor. And be certain that, the farther advanced you find you are in this, the greater the love you will have for God.
Teresa of AvilaDesire to see God, be fearful of losing Him, and find joy in everything that can lead to Him. If you act in this way, you will always live in great peace.
Teresa of AvilaSo dearly does His Majesty love us that He will reward our love for our neighbor by increasing the love which we bear to Himself, and that in a thousand ways.
Teresa of AvilaHalf-instructed confessors have done my soul great harm; for I could not always have such learned ones as I would have desired. They certainly did not wish to deceive me, but the fact was that they knew no better. Of something which was a venial sin, they said it was no sin, and out of a very grave mortal sin they made a venial sin. This has done me such harm, that my speaking here of so great an evil, as a warning to others, will be readily understood.
Teresa of Avila
