Maybe the only threat more grave to our souls than unrighteousness is self-righteousness. Both make us enemies of God, the former by honest rebellion and the latter by dishonest resistance.
If our consciences are working, either by the Spirit or common grace, then the last section of Genesis 19 turns our stomachs. But we need it to turn them in such a way that we appreciate God’s mercy more than we appreciate that we are not like Lot and his daughters.
The girls exaggerated their misfortune, premeditated their manipulation, and dishonored their father in more ways than one. For Lot’s part, it’s almost as if he enjoyed the opportunity to get drunk in his self-pity and forget everything he lost. The sons of this incestuous perversion, Moab and Ben-ammi, were the fruit of selfishness, weakness, and unbelief. Thank goodness Lot’s plot line is over.
Until we get to Ruth, the Moabites. This Moabites married Boaz, the great-grandfather of King David. This Moabite woman is in the genealogy of Jesus. She’s mentioned by name in Matthew 1, the first chapter of the good news of the New Testament.
The point is “Jesus came into the world to save sinners” (1 Timothy 1:15), and not just the “good” sinners. He really identifies with the ungodly, on the cross, and even in His family tree. Our invitation to the Table of communion depends on His mercy, not because we sinned in “natural” ways or have strong “ewww” reflexes.
If we want to compare, let us compare correctly. We compare ourselves with God’s standard, not to others. So we eat and drink and boast, not that we are not like other men, but that God is merciful to us, sinners. He knows what we’re capable of and He is glad to have us here because of Christ’s death and resurrection, and that is amazing.
