We declare to you what was from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and touched with our hands, concerning the word of life—this life was revealed, and we have seen it and testify to it, and declare to you the eternal life that was with the Father and was revealed to us—we declare to you what we have seen and heard so that you also may have fellowship with us; and truly our fellowship is with the Father and with his Son Jesus Christ.The word translated as "fellowship" here is the Greek word koinonia which also means "communion." Koinonia is a close connection. To have koinonia with something or someone is to participate with it and in it. Through our communion with God, we are in communion with all those with whom God is in communion. It is this deeper connectedness of communion which we establish by our faith in Jesus Christ as evidenced through our baptisms (see yesterday's post below).
