Do not live in the past!
Miriam CarrasquilloLot's wife lost her blessing for a moment of weakness; perhaps out of melancholy, or out of love for what he left behind in his past. Lot and his family were warned as they left Sodom and Gomorrah not to look back. That was precisely what his wife did. For one reason or another, Lot's wife disobeyed, and she paid dearly for her disobedience.
The Lord does not want us to live remembering the past, looking at what we left behind, as Lot's wife did. He wants us to forget, if necessary completely, the past, and look at our future; always trusting that God has a better future for us.
