Genesis 7:1 "And the LORD said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation."
Out of all the population on the earth, ONLY Noah and his family were still living in “right standing” with God! Everyone else had given into false doctrines and beliefs and despicable actions. Possibly they “thought” they were honoring God with their sacrifices – just like Cain did with his offering. But they were deceived. Just like many people are deceived about being saved and serving the Lord today. Their actions do not match their words.
Perhaps, as Noah preached to them for 100 years while building the Ark, their leaders told them Noah was nut case. Too radical. Too extreme. “Talking about things that had never happened before as if they were really going to come true.”
Well, that’s kind of where a lot of Christians are today, is it not?
