Among the early converts after Pentecost, as recorded in Acts 2:42, devotion to fellowship, or *koinonia* (G2842), was a priority and a prime objective in their gatherings. This fellowship was not merely about being together but was a dedicated pursuit, distinct from casual interaction. *Koinonia*, the primary Greek word translated as fellowship, embodies two main ideas: to share and take part together in a partnership, and to give to others, emphasizing a shared relationship among all involved. This concept of sharing and partaking together is central to fellowship, highlighting a mutual connection rather than just common activities. The root word *koinos* means common, mutual, or public, referring to what is held in common. *Koinonia* underscores a relationship that binds individuals through shared experiences. This shared life is rooted in a common relationship with Christ, as seen in I Corinthians 1:9, where God calls believers into the fellowship of His Son, Jesus Christ our Lord. True Christian fellowship is primarily a relationship, not merely an activity, producing active sharing in various forms as a result of this bond. Additionally, *koinonia* implies a partnership, where believers are copartners with Christ and each other in His work on earth. This spiritual partnership is formed with godly objectives, the most important being to glorify God. Fellowship, therefore, describes both a community bound by a common life through union with Christ and a partnership working harmoniously to achieve mutual objectives for God's glory and to fulfill the work of Jesus Christ. In the early church, fellowship was no minor matter but stood alongside Bible study and prayer as a vital activity to which they devoted themselves.

Fellowship, as described by the word *koinonia* (G2842), embodies communion, participation, communication, and sharing. This sharing of ourselves and participating in others' lives through correspondence promotes spiritual growth, reflecting the purpose for which God called each of us. Letter writing offers a vehicle for achieving positive, uplifting relationships with those whom God has called as our brothers and sisters in His Family, allowing us to experience the togetherness that pen pals develop. By writing to each other, we can help one another grow, offering encouragement, advice, prayers, and other services during times of trial and difficulty. This act of sharing lives through letters provides the satisfaction of knowing we have contributed to others' well-being, aligning with the essence of *koinonia*.

The concept of fellowship, represented by the Greek word *koinonia* (G2842), is a vital image used to portray the unity of the church of God. This term goes beyond a mere loose collection of friends, as it signifies sharing something or having something in common. In spiritual terms, *koinonia* refers to the shared Christian experience of the gospel, encompassing fellowship with the Father, the Son, and the Holy Spirit, often described as a fellowship in the blood and body of Christ. This fellowship involves the totality of the experience of God's grace, far surpassing a simple acquaintance or friendship, as it is rooted in the blood and body of Jesus Christ and sustained by the Holy Spirit. Furthermore, *koinonia* is not only about what believers share together but also what they share out together. It necessitates a community where Christians actively share their thoughts and lives with one another. True Christian fellowship requires personal engagement and sharing within the church, demonstrating a practical and visible unity. This sharing can vary across different congregations based on local situations and needs, but it remains essential for making the unique and desirable qualities of Christian unity known to the world through genuine love and enjoyment of one another.
