I then make the assumption that God chose that introduction (no doubt
with corrections and emendations) for the first book of the Bible.
I have no proof for that. But that is the beginning of the Bible
I use every day. If God predestined it for my use (and for the whole
church) I assume he wanted it there, and I should take it seriously.
I have to work at the language games for words such a God, Created, Covenant,
Flood, LORD, and for the metaphors and allusions that are used. That
means that exegesis is within a commitment to a certain view of the Bible.
But in any case without Genesis it would be impossible for me to make sense
of the New Testament.
