Im might be missing your point here…are you trying to make the claim its just a story book or do you actually believe it is the only means by which we may know God and be lead to salvation? As a YEC, i believe the latter and I sincerely hope you do as well.
that is completely false…lets start with Genesis chapter 1, Chapter 2, and then Chapters 6&7. Then we move forward to the entire Mosaic writings of the Exodus and in particular the Mosaic Tabernacle…which are a literal example of exactly how God would restore his creation back to the former glory at the end of the Genesis creation week…he would do this by sending His Son to die on the cross as an atonement for the wages of sin is death (Romans 6:23)
You attempt to claim that the death Adam and Eve were forewarnd about in Genesis was only spritual, however, you have no answer for the problem that Christ died physically on the cross as an atonement for the wages of sin = Death
Then we have the entire book of Hebrews (writings of Paul) which illustrate the relationship between the earthly (type) and heavenly (antitype) Sanctuaries and what Christs role in fulfilling the promise given to Eve in the garden of Eden would be!
Then we have the apostle Johns writings in the book of Revelation that link with the book of Hebrews and indeed sum up the entire biblical them of the plan of salvation! you claim this must not be literal…and yet the angels at christs ascention into heaven specifically told us "this same Jesus who you have seen go up into heaven will come again in the same way he went up! I think it universal among mainstream Christians that event is going to happen exactly as described…and we even use the illustration of the story of Elijah when he ran before Ahabs chariot after fire fell from heaven and consumed the alter and sacrifice before Israel and the prophets of Baal …they saw a cloud about the size of a man’s hand on the horizon and it eventually filled the whole sky and it began to rain for the first time in 3.5 years!
Then of course the most famous issue is the 4th commandment…Exodus 20:
8Remember the sabbath day, to keep it holy. 9Six days shalt thou labour, and do all thy work: 10but the seventh day is a sabbath unto the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 11for in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
only a blind man could possibly say there is nothing in TEism that is in conflict with biblical theology…it conflicts with practically all of it!
