Few figures in church history that died before the age of thirty have left such a lasting legacy as Robert Murray M'Cheyne (1813-43). His name is virtually synonymous with the pursuit of personal holiness. M'Cheyne was a living testimony to Scripture's command to "let no one despise you for your youth, but set the believers an example in speech, in conduct, in love, in faith, in purity" (1 Tim 4:12). His ardent praying, preaching, and progress in godliness continue to captivate countless Christians around the world. The model of piety found in M'Cheyne's life and ministry provides needed encouragement for properly understanding biblical spirituality. What was the main fuel of his spirituality? Love for Jesus Christ. In A Communion of Love, Jordan Stone argues that rightly understanding M'Cheyne's spirituality must begin with the fundamental issue of why he pursued the means of grace as he did, before reckoning with how he used those means. Such a reorientation reveals that loving communion with Christ was the all-consuming, driving force for M'Cheyne's vision of the Christian life.
