This is from Dr. King’s book, “strength to love.” I highly recommend it.
From the last paragraph in the Chapter / Sermon called “Our God is able” he says…
Three nights later, our home was bombed. Strangely enough, I accepted the word of the bombing calmly. My experience with God had given me a new strength and trust. I knew now that God is able to give us the interior resources to face the storms and problems of life.
Let this affirmation be our ringing cry. It will give us courage to face the uncertainties of the future. It will give our tired feet new strength as we continue our forward stride toward the city of freedom. when our days become dreary with low-hovering clouds and our nights become darker than a thousand midnights, let us remember that there is a great benign Power in the universe whose name is God, and he is able to make a way out of no way, and transform dark yesterdays into bright tomorrows. This is our hope for becoming better men. This is our mandate for seeking to make a better world.
