There was a civilization before the flood that did not acknowledge their Creator. God sent preachers / prophets to them like Enoch and Noah. The world of that time did not listen. As a consequence, a loving, caring God destroyed billions of people only saving one family of 8.
Today God says He will bring fire to reform this planet, to purge it of Sin and make a new Holy Earth. He warns us that at the time of this purging the culture will be the same “as in the days of Noah”; a time when all men did what was right in their own eyes and evil ruled this planet.
A time when men refused to believe in the God who created them. There are two very telling Scriptures in the Old Testament about God that every person needs to think about and take deep into their own hearts.
The first is Isaiah 55:9…”for as the Heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.”
The second is Psalm 53… “The fool says in his heart, there is no God. They are corrupt, and their ways are vile; there is no one who does good. God looks down from heaven on the sons of men to see if there are any who understand, any who seek God.
Everyone has turned away, they have together become corrupt; there is no one who does good, not even one.”
God said in the book of beginnings (Genesis) that His Spirit would not dwell with men forever.
The God of patience who also created time has proclaimed an end to His patience and an end to time.
