Knowing this on the other hand is a challenge, is it not? I have always thought that my desires were all of the flesh and therefore not of God. If you too feel this way, we are not alone. Even the famous Elisabeth Elliot wrote to her daughter in Let Me Be A Woman, "You know my temperament, so easily convinced
that the will of God is whatever I don't want to do."
We must be cautious and not think more highly of ourselves than we ought. But I do think it is fair to say that the more Christ like we become the more and more our desires will be aligned with His.
