In many ways, testimony is the most democratic—and empowering—of all Christian practices. The entire New Testament is a testimony, a record of experiences that early Christians had with the transformative power of God. Those early believers wrote down theirtestimonies their experiences of sharing their testimonies, and the impace of their testimonyes on the people around them. This basic structure unerlies almost every book in the New Testament—-most of which claim to “witness” or “testify” to the love and grace of Jesus Christ.
