“To praise His name involves more than the mere repetition of the word qadosh [holy]. It includes deep meditation upon God and His attributes and the living of a life of humility in accordance with the precepts laid down in His Word. It is, in other words, the life of faith in Jesus Christ, lived for the glory of God.” (Edward J. Young, The Book of Isaiah, Vol. 1, p. 243).
“[W]hen we have seen God, we then begin to feel and know what we are. Hence springs true humility, which consists in this, that a man makes no claims for himself, and depends wholly on God.” (John Calvin, Commentary on Isaiah at 6:5).
What is the secret of Isaiah’s long and faithful work, even when discouraged? His vision of the thrice holy God ought to encourage you to be faithful in the work to which God has called his church. As you are confronted with God’s holy glory, confess your sinfulness. The live coal is a sign of cleansing. What Isaiah felt symbolically, you experience in Jesus Christ. The glory that Isaiah saw is, according to John 12:41, the glory of Jesus. In him alone is there forgiveness. Catch the vision of God’s holiness, experience the cleansing work of Christ, and in the power of the Holy Spirit go with the good news.
