Properly to hear the story of Genesis 18-19, we must first unlearn all that we thought we knew about the Sodomites.
In the declamation of Isaiah 1, the prophet associates Judah and its rulers with Sodom, for their inhospitality, injustice, and the presumption that they can hide this from God. Zacchaeus, a man characterized by such Sodom-like injustice, is delivered from this as justice is welcomed into his house in the person of Jesus.
In the narrative of Abraham’s conversation with God concerning the destruction of Sodom we find an example of the faithful fulfilment of the calling of the people of God. We are to be those who seek to preserve the world from condemnation by our righteous and life-giving presence within it, tenaciously refusing to abandon it to its destruction.
