It’s remarkable that conservatives don’t understand how Genesis (creation) and John 3:16 (redemption) hang and fall together, because liberals understand it all too well.  In one of the most quoted liberal works of the first part of the 20^th century, Harvard Professor of Church History Kirsopp Lake writes:

 [T]he Fundamentalists are perfectly right in thinking that Genesis is the keystone of all biblical theology (p. 86) …. Apart from a belief in the historic Fall, an historic redemption is meaningless (p. 88).
