Good News for Sarah, Bad News for Sodom
In Genesis 18, God will deal righteously both with Sarah and with Sodom. He guarantees that his promised-seed will be born and that his law will be vindicated. We walk through this narrative in three parts: 1) the promise to Sarah (vv.1-15), 2) the judgment against Sodom (16-22), and 3) the intercession of Abraham (23-33).
