The Martin Luther King Jr. Center for Nonviolent Social Change
Dr. King expresses delight in Mrs. D.A. McGregor's request for a copy of his sermon "Paul's Letter to American Christians." However, since he doesn't have a complete manuscript of the sermon at the time he receives the letter, Dr. King mentions that it will be published in his upcoming book of sermons. The book of sermons would eventually be named "Strength to Love."
