GOD IS GOD and HE is ABOVE ALL THINGS. Above all HE is so HOLY. Now to my understanding with the two verses you need to first of all understand the reason as to why HE regretted in Genesis chapter 6, It was because of the wickedness of human beings, humans had committed such grievous evil in the sight of GOD. If you read from the beginning of that chapter six, the bible says that even the sons of GOD had turned away from GOD. The sons of GOD are the people who have the HOLY SPIRIT of GOD, they had turned away from GOD and had involved themselves with sexual sin with the daughters of the world, so you can see when it comes to sexual sin the **** regretted having created man. Look at Isaiah 59:2. when it comes to sin the **** is ready to separate HIMSELF from man. OUR GOD IS VERY HOLY and for us to have a relationship with HIM we must purge away all the evil of this world.
