From Henri Nouwen:
Just as God cannot be “caught” or “comprehended” in any specific idea, concept, opinion, or conviction, he cannot be defined by any specific feeling or emotion either. God cannot be identified with a good affectionate feeling toward our neighbor, or with a sweet emotion of the heart or with ecstasies, movements of the body, or handling of snakes. God is not just our good inclinations, our fervor, our generosity, or our love. All these experiences of the heart may remind us of God’s presence, but their absence does not prove God’s absence. God is not only greater than our mind; he is also greater than our heart, and just as we have to avoid the temptation of adapting God to our small concepts we also have to avoid adapting him to our small feelings.
