Tozer: the need of Presence

 There is today no lack of Bible teachers to set forth correctly the principles of the doctrines of Christ, but too many of these seem satisfied to teach the fundamentals of the faith year after year, strangely unaware that there is in their ministry no manifest Presence, nor anything unusual in their personal lives. They minister constantly to believers who feel within their breasts a longing which their teaching simply does not satisfy.
