Luke 17:32 is one of the shortest verses in the Bible. It merely says, “Remember Lots’s wife.” In the context, Jesus is speaking of the end times and using the story of Lot to illustrate what will happen. Just like the people in Sodom and Gomorrah continued their wickedness and debauchery right up until the moment that God rained fire and brimstone upon them, so will the world remain in wickedness up until the moment that Jesus comes again.
Jesus then reminds us of Lot’s wife, who, though she escaped the collective judgement of Sodom and Gomorrah, she was still punished by God because she looked back as she was fleeing, going against God’s explicit command.
The principle that we must learn from Lot’s wife is that even though we who know Christ as our Savior have escaped the wrath of God, we can still bring judgement upon ourselves by willfully sinning. If we long for the sin and wickedness that God has saved us out of instead of being grateful for our salvation, then we are disregarding and disrespecting the sacrifice of the Lord Jesus.
