Dr. King's last Sunday sermon was preached in The Washington National Cathedral.
"...You must come to see, American Christians, that it is possible to be self-centered in your self-sacrifice and self-righteous in your self-denial. You may be generous in order to feed your ego, benevolent to feed your pride. So without love, benevolence becomes egotism and martyrdom becomes spiritual pride. Love is the greatest of all virtues. This is the meaning of the Cross, not a meaningless drama on the stage of history, but it is a telescope through which we look out on the long distance of eternity and see the love of God breaking through time. It is an eternal reminder of the power of love over hate. I must say goodbye to you now. Hope this letter finds you strong in the faith. It's possible that I will not get to see you in America but I will meet you in God's eternity. And now unto Him who is able to keep us from falling; and now unto Him who is able to transform dark yesterdays into bright tomorrows. This is the letter and now comes the living of it. God bless you."
--The Rev. Dr. Martin Luther King Jr.
