Love for God is not natural to us. Even in the redeemed state our souls grow cold and we experience feelings of indifference toward him. When we pray, our minds wander and we indulge in woolgathering. In the midst of corporate worship, we are bored and find ourselves taking peeks at our watches. How dissimilar this is to our behavior when we are in the company of those we dearly love.Ouch.
