Marshall Keeble was a Black preacher among the churches of Christ who spent 55 years as a full-time evangelist, much of it in the segregated South. Estimates of how many people he baptized run from about 30,000 to as many as 40,000, and he is credited with planting hundreds of congregations. As president of the Nashville Christian Institute, he took young preachers along on his travels, including a student named Fred Gray, who later became a famous civil rights attorney. Gray said he learned how to preach and so much more from those trips. Keeble navigated prejudice with steadiness and toughness, and kept pointing people to Jesus until his death in 1968. Faithfulness over a lifetime is its own kind of miracle.
