Here’s a good definition of truth from the book, Breaking the Missional Code.
“Truth is not a set of rules to be obeyed, mysteries to be known or evidences to be mastered, but Christ, by whom we know and are known. Truth is not discovered, it is revealed in relationship to both the head and the heart. Therefore, Truth is not something merely known or proclaimed but Someone experienced, tasted, and seen as the Psalmist says, by grace, faith, and presence that not merely knows the Truth but loves Him.”
Pastor Mark Driscoll, Mars Hill Church
