Isaiah 6:5

Here we see, even in God's own servant, what trembling is induced in a near apprehension of God's presence. Men may think lightly of sin, who never felt the galling chain of it; and some poor unawakened sinners, who have never ascertained what righteousness is, by the divine standard, may fancy much of themselves, and of their own righteousness; but when a soul hath once seen God in Christ by faith, and Jesus expiating sin by no less a sacrifice than himself, then all self-complacency and self-righteousness fall to the ground. Reader, I pray you look at Isaiah in this view of him, and hear his confession; then turn to observe Job's account of himself, Job 42:5; and then hearken to the Lord's testimony of him, Job 1:8; then look at David, the man after God's own heart, Psalms 51:1; hearken also to Paul's relation, Romans 7:18, to the end: and if such views do not humble your soul to the very dust of the earth, depend upon it, it is because the Holy Ghost hath never convinced you of sin, and of righteousness, and of judgment John 16:8.
