GENESIS ROOTS: 2 Groups since the beginning

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 Adam knew Eve his wife;

and she conceived, and bare Cain,

and said, I have gotten a man from the LORD.

And she again bare his brother Abel.

And Abel was a keeper of sheep,

 but Cain was a tiller of the ground.

Genesis 4:1,2

There have been 2 groups since the beginning of the children of men on earth. The one group that flows God (Abel) & the group that doesn't (Cain). Nothing has changed among men.
