"But Lot said to them, 'No, my lords, please! Your servant has found favor in your eyes, and you have shown great kindness to me in sparing my life. But I can't flee to the mountains; this disaster will overtake me, and I'll die. Look, here is a town near enough to run to, and it is small. Let me flee to it - it is very small, isn't it? Then my life will be spared.' He said to him, 'Very well, I will grant this request too; I will not overthrow the town you speak of. But flee there quickly, because I cannot do anything until you reach it.' (That is why the town was called Zoar.)" NIV translation
Lot did not see how he and his family could run all the way to the mountains for safety and so he begged the angels to spare a little town called Zoar. They granted his request and we are reminded that God only asks us to do what we can and He will do the rest.
Like Lot, many Christians walk around in fear that they still will not make it to heaven because they do not act perfectly. We are reminded that God spared the little town because that was where Lot and his family were going to be. Jesus has saved us where we are and He does not want us to fear the coming destruction.
