The Old Testament as It Stands, Is It Ambiguous?

I think the Old Testament as it stands remains deeply, deeply ambiguous. The Canaanite stuff is the most obvious example of that. But then when you read it from a Christian lens, part of the meaning of the cross of Jesus seems to me to be that the whole story of Israel and the world gets funneled down onto one point. You can only understand it if you say this isn't just the story of a first century human being called Jesus,. This is the story of God himself, taking responsibility for his creation.
