that which we have seen and heard we declare to you, that you also may have fellowship with us. Yes, and our fellowship is with the Father, and with his Son, Jesus Christ.
Then in chapter 3, verse 1Jo 1:23 , "This is His commandment, that we should believe on the name of His Son Jesus Christ, and love one another as He gave us commandment." So He is our example in our relationship with each other, as we are to love one another as He gave us the commandment.
