Therefore whenever you see evil, look for the good behind it, the good that it is perverting. When you see a parasite, look for its host. When God saw the hate-filled persecutor of Christians, Saul of Tarsus, He saw a powerful mind and will that had been twisted by hate; and He untwisted it and filled it with His love; and thus Saul became Paul, the most powerful missionary in history.
–Peter Kreeft, Practical Theology: Spiritual Direction from St. Thomas Aquinas
