In a sermon I've just listened to, Martin Lloyd Jones said this:
No man should preach unless he preaches a felt Christ
I take it he means that preachers must really know Jesus and preach to the end that their hearers know Jesus and hunger after Him - indeed taste and see Him. I can't think of a more crucial need in preaching.
Unless of course I've got the wrong end of the stick and he means this:
This kind of felt Christ is also important. And would also improve countless pulpits the world over.
Which did the Doctor really intend? I guess we'll never know.
