Daily Luther: Let God Work and You Believe
God’s miracles do not happen so that we can judge and grasp them, but so that we can believe and be comforted by them. Explain to me, if you are so clever, how a large apple, pear, or cherry can be grown through such a small stem, and many similar lesser miracles. Let God work, and you believe, and do not presume to grasp and comprehend Him.
From Luther’s Sermon for St. Stephen in a new edition of his Church Postils, unpublished, but forthcoming from Concordia Publishing House.
