“And because lawlessness will be increased, the love of many will grow cold.  But the one who endures to the end will be saved” (Matthew 24:12-13 ESV).  The crazier the world gets the harder it becomes to love one another.  If we permit it, lawlessness, iniquity, and abounding sin have a way of putting the damper on love.  This affects our endurance.  The endurance expected here is the endurance of loving all people at all times and in all the ways we can.  The saved are those who have endured to overcome the world by love.
