15 As morning dawned, the angels urged Lot, saying, “Up! Take your wife and your two daughters who are here, lest you be swept away in the punishment of the city.” 16 But he lingered. So the men seized him and his wife and his two daughters by the hand, the Lord being merciful to him, and they brought him out and set him outside the city. 17 And as they brought them out, one said, “Escape for your life. Do not look back or stop anywhere in the valley. Escape to the hills, lest you be swept away.” 18 And Lot said to them, “Oh, no, my lords. 19 Behold, your servant has found favor in your sight, and you have shown me great kindness in saving my life. But I cannot escape to the hills, lest the disaster overtake me and I die. 20 Behold, this city is near enough to flee to, and it is a little one. Let me escape there—is it not a little one?—and my life will be saved!” 21 He said to him, “Behold, I grant you this favor also, that I will not overthrow the city of which you have spoken. 22 Escape there quickly, for I can do nothing till you arrive there.” Therefore the name of the city was called Zoar.
God Destroys Sodom
23 The sun had risen on the earth when Lot came to Zoar. 24 Then the Lord rained on Sodom and Gomorrah sulfur and fire from the Lord out of heaven. 25 And he overthrew those cities, and all the valley, and all the inhabitants of the cities, and what grew on the ground. 26 But Lot's wife, behind him, looked back, and she became a pillar of salt.
The text doesn't answer or indicate why Lot's wife looked back, and Googling the question doesn't really turn up very much that's useful. Is there anything in the doctrines of Protestant denominations (the closer to Wesleyan, the better) that explains why Lot's wife looked back?
