I have known Greg Kelley for many years and his passion for unreached people is deep and contagious. “Last 4 Words” captures that passion and challenges us to take Jesus’ very last words seriously and sacrificially—last words are lasting words. Using a terrific blend of Scripture, personal stories, historical examples, and illustrations, “Last 4 Words” powerfully reminds us of the need and priority of those with the least access and response to the gospel. After reading “Last 4 Words” and gaining a fresh understanding of the Great Commission, you may never be the same.
