THE SEQUEL OF THE VISION—THE PROPHET'S SENSE OF UNWORTHINESS.
The vision of God in this life, whether natural or ecstatic, cannot but produce in the beholder a deep feeling of his unworthiness. God "is of purer eyes than to behold iniquity;" even "the heavens are not clean in his sight" (Job 15:15). Man, being never wholly purged from sin while on earth, cannot but shrink from contact with the absolutely Holy. Hence Isaiah's cry (verse 5); and hence, to comfort him, the symbolic action of the seraph (verse 6) and his encouraging words (verse 7).
