Yet they have other two wings to fly with. And being thus composed in reverence and fear to God, they are ready to execute his commands willingly and swiftly, Isa. vi. 1-3, &c. But what is the use Isaiah makes of all this glorious sight? “Woe is me! I am a man of unclean lips,” &c. Oh! all is unclean,—people, and pastor! He had known, doubtless, something of it before, but now he sees it of new, as if he had never seen it. The glory of God shining on him doth not puff him up in arrogancy and conceit of the knowledge of such profound mysteries, but he is more abased in himself by it. It shines into his heart and whole man, and lets him see all unclean within and without. And so it was with Job, Job xliii. 5, 6. “I have heard of thee by the hearing of the ear;” but as long as it was hearsay, I thought myself something,—I often reflected upon myself and actions, with a kind of self-complacency and delight; but now, saith he, since I have seen thee by the seeing of the eye, “I abhor myself and repent in dust and ashes;” I cannot look upon myself with patience,—without abhorrency and detestation. Self-love made me loathe other men’s sins more than mine own, and self-love did cover mine own sins from me; it presented me to myself in a feigned likeness; but now I see myself in my true shape, and all coverings stripped off. Thy light hath pierced into my soul, and behold, I cannot endure to look upon myself. Here now is the true knowledge of God’s majesty, which discovers within thee a mystery of iniquity: and here is the knowledge of God indeed, which abases all things besides God, not only in opinion but in affection, that attracts and unites thy soul to God, and draws it from thyself and all created things. This is a right discovery of divine purity and glory, that spots even the cleanness of angels, and stains the pride of all glory; much more will it represent filthiness, as filthiness without a covering. It is knowledge and science, “falsely so called,” that puffeth up; for true knowledge emptieth a soul of itself, and humbleth a soul in itself, that it may be full of God. He that thinks he knows any thing, knows nothing as he ought to know.
