This message teaches on koinonia, the New Testament word for the deep, shared fellowship believers have in Christ. He grounds this fellowship in the gospel itself, showing that the good news is not only how sinners are saved individually but also the premise for unity within the body of Christ – because believers share one Lord and one salvation, they are bound together as one family.
The message traces the marks of true koinonia and ties it to communion, calling the church to “partake in His Body,” remembering that the Lord’s Supper is itself an expression of the shared life believers have with Christ and with one another. The sermon closes by connecting koinonia to God’s glory, since a united, loving church displays who God is to the watching world.
