The following is from the Preface in J. B. Phillips (1906-1982), Letters to Young Churches.
“The great difference between present-day Christianity and that of which we read in these letters is that to us it is primarily a performance, to them it was a real experience. We are apt to reduce the Christian religion to a code, or at best a rule of heart and life. To these men it is quite plainly the invasion of their lives by a new quality of life altogether. They do not hesitate to describe this as Christ ‘living in’ them.”
