being prepared to sacrifice his own life
I see no indication here that Lot was willing to
voluntarily offer his own fanny...
Genesis 19
19:4 But before they lay down, the men of the city, [even] the men of Sodom, compassed the house round, both old and young, all the people from every quarter:
19:5 And they called unto Lot, and said unto him, Where [are] the men which came in to thee this night? bring them out unto us, that we may know them.
19:6 And Lot went out at the door unto them, and shut the door after him,
19:7 And said, I pray you, brethren, do not so wickedly.
19:8 Behold now, I have two daughters which have not known man; let me, I pray you, bring them out unto you, and do ye to them as [is] good in your eyes: only unto these men do nothing; for therefore came they under the shadow of my roof.
19:9 And they said, Stand back. And they said [again], This one [fellow] came in to sojourn, and he will needs be a judge: now will we deal worse with thee, than with them. And they pressed sore upon the man, [even] Lot, and came near to break the door.
19:10 But the men put forth their hand, and pulled Lot into the house to them, and shut to the door.
19:11 And they smote the men that [were] at the door of the house with blindness, both small and great: so that they wearied themselves to find the door.
