I have never known anyone whose speech communicated such a sense of the reality of God as did the Doctor (Martin Lloyd-Jones) in those occasional moments of emphasis and doxology. Most of the time, however, it was clear, steady analysis, refection, correction and instruction, based on simple thoughts culled from the text, set out in good order with the minimum of extraneous illustration or decoration. He knew that God’s way to the heart is through the mind (he often insisted that the first thing the gospel does to a man is to make him think), and he preached in a way designed to help people think and thereby grasp truth – and in the process be grasped by it, and so be grasped by the God whose truth it is.
J.I. Packer
