In 1 John 1:1 John testifies concerning the Word of life, which is Christ Himself (John 1:1). In verse 2 John says that Life was manifested (in incarnation, John 1:14). This life is Christ, who is the Word.
In verse 3 John says that he reports this Life to us that we may have fellowship. This fellowship is the flow of this Life, between us and other believers and between us and God. In Revelation 22:1 this fellowship is portrayed by the river of life flowing in New Jerusalem.
In verse 5 John tells us that “God is light and in Him is no darkness at all.” In 1 John 1, as we saw in other verses in prior posts, life and light are coupled. God is light, and His city, New Jerusalem, is a city of light.
In verses 6 and 7 walking in this light and having fellowship are joined. This walk, this fellowship, this flow of life, is maintained because “the blood of Jesus His Son cleanses us from every sin.”
Until the redemption of our mortal bodies at the Lord’s return, we must admit that we have the nature of sin in our flesh and that we commit sins in our living (verses 7-9). When the light exposes us, we confess our sins, and we are forgiven and cleansed. This restores both our walk in the light and our fellowship of life.
This exposing, confessing, and cleansing is an integral part of our Christian life today. The shining light and the flowing life are also part of our Christian life today and will characterize New Jerusalem in eternity.
