From Drew Hunter:
So, where did it come from? Thankfully, it’s used all over the place these days. My hunch is that the person who put feet on it and therefore caused it to run throughout this generation is Jerry Bridges. Perhaps surprisingly, this theme wasn’t in his first and probably most well known book, The Pursuit of Holiness. It wasn’t until after writing this book that he began to more clearly see and stress the centrality of the gospel in the life of the Christian (See second paragraph here). Following that book, however, he began emphasizing the centrality of the gospel for everyday life and often used the phrase, “preach the gospel to yourself,” to express it.
While I think Bridges has promoted the phrase more than anyone, he got it from someone else. In the preface to The Discipline of Grace, a book wherein one of the chapters is titled, “Preach the Gospel to Yourself,” he says, “I… owe a debt of gratitude to my friend Dr. Jack Miller, from whom I acquired the expression, “Preach the gospel to yourself every day”
Read the whole thing.
