All of the Israelites left Egypt, but in the desert many of them had second thoughts and wanted to return. In the same way, some resolve to avoid sin, but they look back at Sodom even while fleeing it. They give up their sins, but go right on talking about them, desiring them. If you want to live a devout life, you are not only required to stop sinning but also to lose your appetite for it.
–Saint Francis de Sales (1567-1622)
