This an excerpt from the conclusion to MLK’s 1959 sermon, “A Tough Mind and a Tender Heart.”
I am thankful that we worship a God who is both tough minded and tenderhearted. If God were only tough minded, he would be a cold, passionless despot sitting in some far-off Heaven “contemplating all,” as Tennyson puts it in “The Palace of Art.” He would be Aristotle’s “unmoved mover,” self-knowing but not other-loving. But if God were only tenderhearted, he would be too soft and sentimental to function when things go wrong and incapable of controlling what he has made. He would be like H. G. Well’s loveable God in God, the Invisible King, who is strongly desirous of making a good world but finds himself helpless before the surging powers of evil. God is neither hardhearted nor soft minded. He is tough minded enough to transcend the world; he is tenderhearted enough to live in it. He does not leave us alone in our agonies and struggles. He seeks us in dark places and suffers with us and for us in our tragic prodigality.
At times we need to know that the Lord is a God of justice. When slumbering giants of injustice emerge in the Earth, we need to know that there is a God of power who can cut them down like the grass and leave them withering like the Greek herb. When our most tireless efforts fail to stop the surging sweep of oppression, we need to know that in this universe is a God whose matchless strength is a fit contrast to the sordid weakness of man. But there are also times when we need to know that God possesses love and mercy. When we are staggered by the chilly winds of adversity and battered by the raging storms of disappointment and when through our folly and sin we stray into some destructive far country and are frustrated because of a strange feeling of homesickness, we need to know that there is Someone who loves us, cares for us, understands us, and will give us another chance. When days grow dark and nights grow dreary, we can be thankful that our God combines in his nature a creative synthesis of love and justice that will lead us through life’s dark valleys and into sunlit pathways of hope and fulfillment.
