1 John 1:1-2 (ESV)
That which was from the beginning, which we have heard, which we have seen with our eyes, which we looked upon and have touched with our hands, concerning the word of life—  the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us—
And proclaim to you the eternal life, which was with the Father and was made manifest to us—
We proclaim to you the eternal life, that is Jesus Christ who is eternal being from the beginning with the Father. Of course this is what Christianity is about, eternal life. In fact, one might say it isn’t so much about it as it is eternal life. Jesus Christ, the life made manifest is proclaimed to us that we might have eternal life in Him. This comes through forgiveness and forgiveness alone. This eternal life is made manifest nowhere but in the resurrection. It is the resurrection that we share in Christ proclaimed to us. A resurrection to which we have been joined in the death of our old Adam in Baptism, and the raising of our new man there also. We have this life even now. It isn’t something for which we wait, but even now we have eternal life, and live and serve Christ in his kingdom.
