Even though he managed to have sex twice with his daughters whilst drunk? Whatta guy
How do you know that they did not get him extremely drunk, cover their faces, and then come to him?
Also, it is 2Peter that calls Lot righteous not Hebrews. Plus, you must keep in mind that though a Bible writer may have recorded specific sins and foolish acts of an individual does not mean that the person could not also have been righteous. Only Jesus was completely righteous and sinless. Though Noah, Abraham, Moses, etc. were counted faithful (Hebrews 11:7-29), they occasionally disobeyed God’s will, and acted foolishly or cowardly. God never blessed their disobedience, only their faithfulness.
Consider the harlot Rahab. While God did not condone her being a prostitute, she was “justified by works when she received the messengers and sent them out another way” (James 2:25).
Simply because God graciously saved Rahab from the destruction of Jericho, does not mean that God condoned her past sexual sins. Similarly, just because Peter called Lot righteous does not mean that Lot was perfect. Even the apostle Peter, who also served as an elder in the church, was guilty at one time or another of having a lack of faith, denying that he knew the Lord, and hypocritically withdrawing himself from Gentiles.
Though Lot’s offering of his daughters to the sodomites is inexcusable, Genesis 19 clearly indicates the distinction between the righteousness of Lot and the wickedness of the inhabitants of Sodom. The sodomites even hinted at such when they declared that Lot “keeps acting as a judge” (Genesis 19:9). This was the distinction Peter made—not that Lot was perfect, but that he remained uncontaminated by the actions that were prevalent throughout Sodom. Like Christians today who strive to walk in the light, though they are imperfect (1 John 1:5-10), Lot was a righteous man, who also made some memorable mistakes.
