Everything's Founded in Genesis

Do you realize that, ultimately, every single biblical doctrine of theology directly or indirectly is founded in Genesis 1-11? Why did Jesus die on a cross?—Genesis 1-11. Why is He called “the last Adam” (1Co 15:45)?—Genesis 1-11. Why do we sin?—Genesis 1-11. Why is there death in the world?—Genesis 1-11. Why do you have a seven-day week?—Genesis 1-11. Why do we need new heavens and a new earth?—Genesis 1-11. Why is marriage between one man and one woman?—Genesis 1-11. Is it therefore important? Genesis 1-11 is the foundational history for the whole rest of the Bible!”
