Does it make a difference that the God Christians claim to worship has revealed himself as triunethe Father, Son, and Holy Spirit? Does this fundamental truth of biblical authority have an effect on a believer's personal fellowship with God? Puritan theologian John Owen recognized the great need for every believer to understand the triune God. Communion with the Triune God revisits the truth presented by John Owen and challenges all believers to truly recognize and appreciate the ministry that God the Father, God the Son, and God the Holy Spirit have in their lives. This work of John Owen encourages Christians to enjoy true communion with each person of the triune God.
