A joyous church can grow only in an environment of love, faithfulness, and Christian fellowship. The reader of this book will find that Christian fellowship is built upon three basic tenets of biblical faith and practice, namely a Covenant Relationship with God, the Lordship of Jesus Christ, and the Indwelling Presence of the Holy Spirit. This book was written as a Bible study for individual reading, but it is readily adaptable for use in group Bible study. Extensive references to Holy Scripture are provided to benefit the serious reader. The subject matter of this book is God the Father, God the Son, God the Holy Spirit, and the role of each in growing a joyous church.
