Which God do you prefer? The God of the Old Testament or the God revealed in Jesus in the New Testament?

In today's message, Pastor Dave Flannery talks about Jesus' use and affirmation of the Old Testament scriptures.
His message from Matthew 5:17-20 shows us that Jesus did not do away with the law and the prophets, but He fulfilled them in order to bring us the righteousness we lack.

Jesus Christ is the same yesterday and today and forever. (Heb. 13:8)
