There are many signs that the judgment of God is upon the church as never before. Unless the early sacrificial spirit is recaptured, I am very much afraid that today's Christian church will lose its authenticity, forfeit the loyalty of millions, and we will see the Christian church dismissed as a social club with no meaning or effectiveness for our time, as a form without substance, as salt without savor. The real tragedy, though, is not Martin Luther King's disillusionment with the church — for I am sustained by its spiritual blessings as a minister of the gospel with a lifelong commitment: The tragedy is that in my travels, I meet young people of all races whose disenchantment with the church has soured into outright disgust.
