Jonathan Edwards’ Notes on the Bible can be found in vol. 2 of his works (both in the Banner of Truth edition as well as in the Hendrikson set). This work is of supreme value to the minister of the Gospel or those pursuing the ministry because of the depth of theological insight found in these short writings. Edwards’ worked his way through many portions of Scripture writing down his thoughts about or conclusions concerning these passages. If I had to recommend only one or two passages to read I would direct you to #460 (titled “The Book of Solomon’s Song, no common love song”) and #140 starting from his comments on 2 Peter 1:16. You can find the section on the Song of Songs here. His thoughts on 2 Peter can be found here. So that you will see the depth of Edwards’ understanding into the Scritpure consider the following portion:
2. This glory that appeared in the person of Christ, did exactly resemble that excellent glory that the apostle speaks of, out of which the voice came, verse 17. For there was there in the mount an external glory, as a visible symbol of the presence of God the Father, and by which he was represented; as well as an external glory in God the Son, viz. that bright cloud that overshadowed them. There was a glory in that cloud that the apostle calls an excellent glory. When it is said in the evangelists that a bright cloud overshadowed them, it is not meant such a light or white cloud as shines by a cast of light upon it from some shining body, such as are some clouds by the bright reflection of the sunâ€™s light; but a cloud bright by an internal light shining out of it, which light the apostle calls an excellent glory. It probably was an ineffably sweet, excellent sort of light, perfectly differing from and far exceeding the light of the sun. All light is sweet, but this seems to have been immensely more sweet than any other that ever they had; impressing some idea which we cannot conceive, having never seen it, as we can conceive of nothing of light more than we have seen; we could have conceived of no such light as the light of the sun, had not we seen it, nor of any colour, blue, red, green, purple, nor any other. God doubtless can excite other ideas of light in our minds besides any of those that we have had, and far exceeding them; a light affording sweetness and pleasure to the sight, far exceeding all pleasure of the grosser and inferior senses. Therefore, Peter the apostle, that writes this epistle, was exceedingly delighted with it in the time of it, which made him say, â€œIt is good for us to be here;â€ and made him talk of building tabernacles, and thinking of spending the rest of his days there; and he still (though now old and near his end, verses 13, 14.) retains a lively sense of the exquisite gloriousness and pleasantness of that light, when he expresses himself as he does here, calling it the excellent glory. And there probably was an exact resemblance between the glory that the disciples saw in Christâ€™s face, and that which they saw in this cloud, which declared him to be the Son of God; for they saw him to be his express image.
