Which Came First, the Chicken or the Egg?

We discussed the Gift of Tongues last week because many people have been taught differently about it. When preparing for this week's sermon, I thought I was going to continue our following of Jesus, but my thoughts went to another topic where people have been challenged: the Law and Faith.

Where do these critical components of our Christian faith intersect? What is primary and which is secondary? Or are they both primary? Does what is written in the New Testament essentially nullify the Law?
