Okay, this is my summary of years of diligent study, bible college, and countless sermons and books.
The Old Testament was the story of a particular ancient tribe and their impressions of God. It is completely irrelevant for us now except for any gems we can pull from it (sure you can make it about Jesus etc, but so what, means nothing now, and in fact completely distracts us from who we are now).
Jesus came from that tribe and actually spent most of his time telling them they had it completely wrong. He then sorted out the whole relationship to God thing, helped us to see how incredibly loving and personal God is, helped us to realise he is all in all and we have nothing to worry about.
Mankind has been trying to return to the mish mash of tribal Judaism in the name of Christ ever since - completely missing the point of everything Jesus did.
What a mess we have made of something so incredibly simple - God 100% in us and us 100% in God - complete freedom to live loved!
