It describes a flood that was from the perspective of all man could know and see. Did man know of the unknown world on earth? Why would God destroy all the earth that we know today, when man only lived in a space no larger than was needed to keep them close enough to Noah, to hear God's warnings that came from Noah's mouth?
Read the following carefully, please.
2 Peter 2:5
If He didn't spare the ancient world, but protected Noah, a preacher of righteousness,
and seven others, when He brought a flood on the world of the ungodly.
Note! ....
on the world of the ungodly.
It was the world of the ungodly that was destroyed. All the world of the ungodly.
Grace comes before judgment! All evil men and women had to hear the warnings of Noah before judgment could come.
Genesis 6:7a
And the Lord said, I will destroy man whom I have created from the face of the earth.
God did not say he would destroy the earth! Did, He? No! But, destroy all man on the face of the earth! Animals in that area of men? They would have to be destroy, too as to destroy man. Man was yet low in numbers because man was still in his infancy stage.
If what you claim were truth? How could men on the other side of the world have been so warned by hearing Noah preach? There were no men elsewhere that would be out of being able to access Noah.
So.. God was going to shoot a flea with a cannon? Yes.. God destroyed the world... where man was living.
And the Lord said, I will destroy man whom I have created from the face of the earth.
Do we have?
God so loved the world that he gave his only begotten son. Did God give his son to save the mountains and trees, and oceans? It all depends how the word "world" was used. Doesn't it?
All man knew at the time of Noah was the world they had direct contact with. All of that known world, and all life in it, was destroyed by a controlled flood from God.
Will it be... Insight. Or, flight?
If every species of all things that creep on the earth were to be gathered to be saved? Noah would have had to build a massive fleet of arks? If you want secular scientist to feel justified in their rejection of God? Your thinking makes them justified. An accurate and detailed understanding of the Bible leaves them angry and fuming. Your thinking is a comfort to them.
Like I said... I refuse to be stupid. God makes wise the stupid. If they would only accept correction when its given to them. We (myself included) are all stupid when left to our own way of seeing things. His ways are not our ways. His thoughts are not our thoughts. There is a way that seems right to a man. But, its way leads to death.
What separates the wise believer from the foolish? One knows he is stupid. The other does not. I know I am stupid. Because what I am showing you dumbfounded me to discover how wrong I had been because I was accepting tradition without knowing better. I know I am stupid. Do you? We all are before God until He can correct us. I still have much to be corrected in. One day at a time.
Proverbs 12:15
The way of a fool is right in his own eyes,
But he who heeds counsel is wise.
