Biblical key doctrines have their roots in Genesis 1-11. This is why these chapters should be defended by Christians---not undermined or ignored by them.
And the LORD said unto Cain,
Why art thou wroth? and why is thy countenance fallen?
If thou doest well, shalt thou not be accepted?
and if thou doest not well, sin lieth at the door.
Genesis 4:6,7
So too in the end times---a WARNING is given to spiritual "Cain" (via the 3 angels message).
