If there is an Enemy of Souls (and I have not the slightest doubt that there is), one thing he cannot abide is the desire for purity. Hence a man or woman’s passions become his battleground. The Lover of Souls does not prevent this. I was perplexed because it seemed to me He should prevent it, but He doesn’t. He wants us to learn to use our weapons.
Elisabeth Elliot, Passion and Purity (Revell, 2002), p. 28.
