Isaiah 6:5
“Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts”— Isaiah 6:55Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts. (Isaiah 6:5).
A sudden realization of the holiness of God brought with it a sense of Isaiah’s own unfitness for the divine presence. He felt in his inmost being that he was defiled and unclean, even as, long years after, Peter the fisherman felt, when consciously in the presence of the Creator Incarnate (Luke 5:88When Simon Peter saw it, he fell down at Jesus' knees, saying, Depart from me; for I am a sinful man, O Lord. (Luke 5:8)), and as Job felt long before when a sense of the majesty of Jehovah burst upon his soul (Job 42:5, 65I have heard of thee by the hearing of the ear: but now mine eye seeth thee. 6Wherefore I abhor myself, and repent in dust and ashes. (Job 42:5‑6)). It is always thus when one comes to such a recognition of the holiness, power, and majesty of God. Unclean lips come from an unclean heart, and this is part of our inheritance from Adam. Isaiah confessed his own sinfulness and that of all the people among whom he moved; “For all have sinned, and come short of the glory of God” (Rom. 3:2323For all have sinned, and come short of the glory of God; (Romans 3:23)).
“God of all power, and truth, and grace,
Which shall from age to age endure,
Whose Word, when heaven and earth shall pass,
Remains and stands forever sure.
Purge me from every evil blot;
My idols all be cast aside:
Cleanse me from every sinful thought.
From all the filth of self and pride.
Give me a new, a perfect heart,
From doubt, and fear, and sorrow free;
The mind which was in Christ impart,
And let my spirit cleave to Thee.”
—Charles Wesley.
