That verse has NOTHING TO DO WITH FELLOWSHIP WITH GOD, and yet you continue to push that falsehood. Shameful.
What about this one?:
"That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. And these things write we unto you, that your joy may be full. This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness" (1 Jn.1:3-9).
The people who Peter addressed here had their life in Christ Jesus just like all of the other members of the Body of Christ:
"And this is the record, that God hath given to us eternal life, and this life is in his Son" (1 Jn.5:11).
These Jewish Christians are told that the eternal life which has been given to them is 'in" the Son. This can only be in regard to how the sinner is made
"alive together with Christ":
"even when we were dead in our transgressions, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him in the heavenly places in Christ Jesus" (Eph.2:5-6).
This speaks of the Christian's total identification with the Lord Jesus, a truth which is true for only those who are in the Body of Christ. Our life which is in Christ is the same thing spoken of in the following passage:
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, who is our life, shall appear, then shall ye also appear with him in glory" (Col.3:1-4).
The Christian has been given eternal life, and "this life is in the Son"..." Christ is our life" and our "your life is hid with Christ in God." These verses are in regard to a total identification with the Lord Jesus and speak of our "position" in Christ, being risen with Christ and being seated with Him in heavenly places.
