But in order to arrive at the perfect love of Jesus Christ, we must adopt the means. Behold, then, the means which St. Thomas Aquinas gives us:
1. To have a constant remembrance of the benefits of God, both general and particular.
2. To consider the infinite goodness of God, who is ever waiting to do us good, and who ever loves us, and seeks from us our love.
3. To avoid even the smallest thing that could offend him.
4. To renounce all the sensible goods of this world, riches, honors, and sensual pleasures.
--St. Alphonsus Liguori, The Holy Eucharist
