New Defender's Study Bible Notes
2:7 just Lot. Despite Lot’s compromises, God still considered him a “just,” or “righteous” man, justified through the faith which led him to go with Abraham to Canaan, probably also worshipping at Abraham’s altar (Genesis 12:8).
2:7 conversation. That is, “behavior.”
2:8 righteous man. Despite his unfortunate end, Lot is recognized by Peter as having been “just” (II Peter 2:7) and “righteous.” Even believers may become “castaways” (I Corinthians 9:27) in this life (even though they are still “just and “righteous” through faith in Christ and therefore will be in heaven in the future life) if they persist in a materialistic life style.
