The lukewarm soul, that soul who would like to be worldly without ceasing to be a child of God. You will see such one at one moment prostrate before God, his Savior and his Master, and the next moment similarly prostrate before the world, his idol. Poor blind creature, who gives one hand to God and the other to the world, so that he can call both to his aid, and promise his heart to each in turn! He loves God, or rather, he would like to love Him, but he would also like to please the world. Then, weary of wanting to give his allegiance to both, he ends by giving it to the world alone.
