Perhaps the best way in which I can stimulate thought, and give some little help in this matter, is to make the blunt statement that I have not followed this practice in my ministry (to give altar calls). And let me give some of the reasons which have influenced me in that respect. I shall not attempt to state them in any exact systematic order, but here is roughly the order. The first is that it is wrong, surely, to put direct pressure on the will. Let me explain that. Man consists of mind, affections and will; and my contention is that you should not put direct pressure on the will. The will should always be approached primarily through the mind, the intellect, and then through the affections. The action of the will should be determined by those influences. My scriptural warrant for saying that is Paul’s Epistle to the Romans chapter 6, verse 17, where the Apostle says: ‘God be thanked that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine that was delivered you.’

Lastly, and only lastly, Homiletics. This to me is almost an abomination. There are books bearing such titles as The Craft of Sermon Construction, and The Craft of Sermon Illustration. That is, to me, prostitution.

Gotta love the doctor. How true is this.
What is the chief end of preaching? I like to think it is this. It is to give men and women a sense of God and His presence. As I have said already, during this last year I have been ill, and so have had the opportunity, and the privilege, of listening to others, instead of preaching myself. As I have listened in physical weakness this is the thing I have looked for and longed for and desired. I can forgive a man for a bad sermon, I can forgive the preacher almost anything if he gives me a sense of God, if he gives me something for my soul, if he gives me the sense that, though he is inadequate himself, he is handling something which is very great and very glorious, if he gives me some dim glimpse of the majesty and the glory of God, the love of Christ my Saviour, and the magnificence of the Gospel. If he does that I am his debtor, and I am profoundly grateful to him. Preaching is the most amazing, and the most thrilling activity that one can ever be engaged in, because of all that it holds out for all of us in the present, and because of the glorious endless possibilities in an eternal future.”
