We especially meet Jesus in the Gospels, the books of Matthew, Mark, Luke, and John (found in the New Testament). The Gospels are narratives of the life and work of Jesus. Eyewitnesses to the words and life of Jesus wrote Matthew and John. Two others—Mark and Luke—were written by those who spoke with eyewitnesses. The Holy Spirit uses these texts so that the reader sees, hears, experiences, and ponders the life of Jesus.
