God has not changed, just the covenant

As new Christians we wrap ourselves in the New Testament, usually starting with John & Romans. We rightfully should. But at some point we need to dive into the Old Testament, because it is here that we learn about our God. It make sense. The New Testament has 70 to 100 years of history, where the Old Testament has 5000+ of history. History showing how God interacts with man, whom he made in His own image.
