Genesis 18-19 reveals God's character through His interactions with Abraham and Lot. God personally shared His plans with Abraham, demonstrating how He reveals divine intentions to those who follow Him faithfully. Abraham's intercession for Sodom shows how justice and mercy work together in God's nature. Meanwhile, Lot's story illustrates the dangers of compromising with sin, leading to spiritual blindness and poor judgment. Yet even in the aftermath of terrible mistakes, God's redemptive power shines through, as seen in how the lineage from Lot's sin eventually led to Ruth, an ancestor of Jesus.
