Why would you trust the guy with all the big guns who has just blown up most of the world? No wonder God has to reassure Noah – ‘It’s not going to happen again.’ (Genesis 8 v 21); ‘I’m never not going to do it again’ (9 v 11); ‘I promise I will never do that again’ (v 15). He even does the God alternative to tying a knot in his handkerchief, (the illustrious rainbow) to make sure that it’s a done deal, IT WILL NOT HAPPEN AGAIN.
Why should the almighty, all powerful God go to such trouble? Hadn’t he already saved the man and his family? What more would Noah want?
God wanted relationship, not fear. That’s what covenants are about – relating, agreeing together, bonding.
God wanted Noah to know that HE IS FOR LIFE. ‘Value all life.’ ‘Be fruitful.’ ‘Multiply.’ ‘Fill the earth.’ ‘Increase in numbers.’ ‘Enjoy this new world to the full.’ He was into creating more life, and living it to full measure – not reduced by anyone or anything.
So we see God’s side of the bargain was to promote, protect and maintain life on earth. What was required of Noah and mankind? To do right because it is right, and not because of the fear of punishment. And as far as I know, that has not changed.
