As the temple shook, the building was completely filled with smoke, possibly representing God’s glory (1 Kings 8:10). Isaiah’s repentant response was entirely appropriate, “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 my eyes have seen the King, the Lord of hosts” (6:5).
Repentance is the missing ingredient in most of our lives. Just as pruning a tree removes branches that stifle growth, deep brokenness and repentance remove the decay in our lives. If we’re not careful, success can assassinate the soul and Bible knowledge can puff us up. As a result, we can easily become prideful and arrogant. If we don’t cry, “Woe is me,” and admit that we are spiritually bankrupt, we will never experience a deep work of God’s Spirit.
When our heart is revived and awakened to the things of God, dead churches and carnal Christians are convicted of their barrenness, and conservatives are deeply challenged by their lack of spiritual depth. Many have head knowledge, but not heart knowledge.
