The scriptures are called the lively oracles of God: not only because they are generally made use of to beget in us a new life, but also to keep up and increase it in the soul. The apostle Peter, in his second epistle, prefers it even to seeing Christ transfigured upon the mount. For after he had said, chap. 1:18. ‘This voice which came from heaven we heard, when we were with him in the holy mount'; he adds, ‘We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light shining in a dark place, until the day dawn, and the day-star arise in your hearts': that is, till we shake off these bodies, and see Jesus face to face. Till then we must see and converse with him through the glass of his word. We must make his testimonies our counselors, and daily, with Mary, sit at Jesus’ feet, by faith hearing his word. We shall then by happy experience find, that they are spirit and life, meat indeed and drink indeed, to our souls.
