In Isaiah 6, we have a tremendous sense of God’s holiness – “Holy, holy, holy is the Lord of hosts” (v.3) – and a deep awareness of our own sinfulness – “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” (v. 5). These things – God’s holiness and our own sinfulness are made known to us by divine revelation: “my eyes have seen the King, the Lord of hosts” (v.5). When we take these things seriously – the holiness of God, our own sinfulness and the divine revelation through which come to know both the holy God and our sinful selves, our approach to the problem of evil is much more than just another contribution to an intellectual debate. We’re doing much more than discussing different ideas and evaluating the various arguments that have been put forward. We commit ourselves to the Lord. We put our trust in Jesus Christ, the Saviour of sinners. Through faith in Him, we are declared righteous by the God of perfect holiness. From this perspective, our approach to the problem of evil must always be both a confession of our own faith and an appeal to sinners to “look to the Lord and be saved” (Isaiah 45:22).
