In verse 2, this One Who Is the Word of Life, he declares plainly to be the Eternal Life that was with the Father. In these two verses we have a most personal and intimate encounter with the God/Man Who Is the Sent One from the Father. (See John 5:22-24, 6:29)
Verse three lays out John's reason for giving us this introduction to his Beloved Lord. It is that we may have fellowship with the Apostles in a spiritually Hands-On way in order that we may have a spiritually Hands-On fellowship/relationship with the Heavenly Father and His Beloved Son, Jesus Christ. This is in keeping with John's record of our Lord's High Priestly prayer in John 17:20 where our Jesus prays for "them also which shall believe on Me through their (the Apostles) word." The power of the Gospel is in this historic Apostolic Witness, the Witness that we are called to spiritually encounter. They did not speak of some myth!!
It is intriguing that while John presents Jesus as the Eternal Life that is with the Father from the beginning, his focus is not primarily our eternal life in him. I believe that's to be understood in his words, but he seems to be emphasizing that our life in Christ is first of all to be one of fellowship with the Father and His Son. There is no indication of a "get out of hell free card" salvation in John's thinking. This Eternal Life, this life in Christ Jesus, brings us into fellowship with the Most High God, and this is no mere nodding acquaintance of which he speaks..
I have heard the cutesy description of fellowship as two fellows in one ship. That is dreadfully inadequate in John's context. The only validity to such a trite example might be seen if we see Christ Jesus as our Ark and us floundering, drowning, trying to walk on water, and His mighty right hand drawing us to the safety of the Ark. Or perhaps we being in Christ Jesus and the waves of this world and the storms and lightning of our flesh threaten to sink us, and again our sweet Jesus calls our, “Peace be still”, and all is at rest.
It is in this intimate, continual fellowship with our Savior who is Eternal Life, our Ark of Safety, that we find true Joy and that to the fullest.
Next time: the believers walk in fellowship with his Lord through this defiled and fallen world. 1 John 1:5-2:2
