This study’s main contribution is its aim to reorient the common perception surrounding M’Cheyne’s pursuit of holiness. It 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 driving force for M’Cheyne’s vision of the Christian life.
