Apologist and ethicist Bill Muehlenberg writes:
Over his many years as a preacher, Martyn Lloyd-Jones would have uttered tens of thousands of words about holiness. This was part of the many millions of words he spoke on basic Christian truths, such as the nature and attributes of God, the life and work of Christ, and the content and glory of the gospel.
What I am attempting to do here is much more modest in aim. I am referring to just one of his sermons as found in just one of his books. But what is found there is certainly representative of his broader teachings on the subject, and is well worth sharing here.
In the 1940s the Doctor did a series of sermons on the First Epistle of John. In the 1990s Crossway Books turned them into a series of five volumes. In vol. 3, Children of God, we have chapter three, entitled simply, “Holiness”. Although just a dozen pages in length, it packs a punch as it delivers many valuable spiritual truths.
