We should observe in these verses–what a solemn warning our Lord gives us against unsound profession. Lot’s wife went far in religious profession. She was the wife of a “righteous man.” She was connected through him with Abraham, the father of the faithful. She fled with her husband from Sodom, in the day when he escaped for his life by God’s command. But Lot’s wife was not really like her husband. Though she fled with him–she left her heart behind her! She willfully disobeyed the strict injunction which the angel had laid upon her. She looked back towards Sodom–and was at once struck dead! She was turned into a pillar of salt, and perished in her sins! Remember her–says our Lord, “Remember Lot’s wife!” Lot’s wife is meant to be a beacon and a warning to all professing Christians. It may be feared that many will be found like her, in the day of Christ’s second coming. There are many in the present day, who go a certain length in religion. They speak the “language of Canaan.” They use all the outward ordinances of religion. But all this time, their souls are not right in the sight of God. The world is in their hearts–and their hearts are in the world. And, by and bye, in the day of sifting–their unsoundness will be exposed. Their Christianity will prove rotten at the core! The case of Lot’s wife will not stand alone. Let us remember Lot’s wife, and resolve to be real in our religion. Let us never rest until we have the true grace of God in our hearts–and have no desire to look back to the world.
