As Abraham pleads for the lives of the righteous in Sodom and Gomorrah, we see a picture of Hell in God’s destruction of the entire valley in which Sodom and Gomorrah were located, and a picture of redemption in the saving of Lot and his family (excepting his wife).
This event served throughout the Bible as a reminder both to God’s people and to the unsaved that God takes sin very seriously. This message was most strikingly reinforced when God punished His own Son on the cross for the sins of His people.
In the light of these events, we are urged to fear God and to have nothing to do with sin. If we are believers, we need to renew our struggles against sin in every part of our lives; if we are unbelievers, we need to run to Christ for salvation now, as Lot ran from Sodom, before the judgment falls and it is too late.
