Martyn Lloyd-Jones, Preaching and Preachers, Zondervan, 1972, p. 324.
[The Holy Spirit brings] clarity of thought, clarity of speech, ease of utterance, a great sense of authority and confidence as you are preaching, an awareness of a power not your own thrilling through the whole of your being, and an indescribable sense of joy. You are a man “possessed,” you are taken hold of, and taken up. I like to put it like this – and I know of nothing on earth that is comparable to this feeling – that when this happens you have a feeling that you are not actually doing the preaching, you are looking on. You are looking on at yourself in amazement as this is happening. It is not your effort; you are just the instrument, the channel, the vehicle: and the Spirit is using you, and you are looking on in great enjoyment and astonishment. There is nothing that is in any way comparable to this.
