Meditations in 1 John : 5 : Walk in the Light
1 John 1:6,7 If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
In the early part of this twenty first century crusading atheists have attacked God and the Church and one of the key prongs of their attack has been based on poor examples of Christianity, people whose lives have not lived up to the call of Jesus. There is in these verses a call to a great separation and it is a call to every believer.
Now it may be that John was speaking out in these verses against those who purported to be believers in that time, yet whose lives could hardly be distinguished from the rest of the world. Some religious groups said it was all right to live how you wanted. It was the argument that Paul went against in his letter to Rome: “What shall we say, then? Shall we go on sinning so that grace may increase? ….. Shall we sin because we are not under law but under grace?” (Rom 6:1,15)
John is a great one for calling Christians to live godly lives, lives that are pure and righteous. He does it by contrasting light and darkness. We have already touched on it in the previous verse meditation. Referring to Jesus in his Gospel, John wrote, “The light shines in the darkness, but the darkness has not understood it.” (Jn 1:5) and “The true light that gives light to every man was coming into the world.” (Jn 1:9)
John uses light and darkness to describe right and wrong living, because the analogy is so clear – light and darkness cannot exist in the same space at the same time. If you go into a dark room and turn on the light the darkness disappears. It is as simple as that. So, says John, Jesus is light and if you claim to be united with him in fellowship, and yet carry on sinning, that is proof that Jesus’ light is not in you, you are not in fellowship with him and all you say is a lie about being a believer.
When we talk about becoming a Christian we talk about inviting Jesus into your life. Now if you do that – genuinely – then his light will prevent you from sinning. Another way we put it is to talk about the Holy Spirit coming to live in us. He is light and if He genuinely lives in us and we fellowship with Him, then darkness cannot remain in us, sin cannot remain in us. The key word is ‘fellowship’. In his Gospel, John remembered Jesus, at the Last Supper speaking of similar things: “I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit.” (Jn 15:5) Remaining in, or, as the older versions had it, ‘abiding in’ simply means living in harmony with Jesus, fellowshipping with him.
Sanctification – that change of life to become more like Jesus – is both an instant and a gradual thing. It is instant and starts from the moment we come to Christ and he places his Holy Spirit within us. At that point the goal of our life, all of our aims, changes. From that moment living for God becomes the all-important thing; that’s what we mean when we talk about surrendering our lives to Him. From that moment on, His will is the all-important thing for us, but the trouble is that often there are things we haven’t realized God wants to change and, in fact, the change will take years and years. But whenever we recognize something that is not right, we must deal with it immediately – for it is darkness and it can no longer exist within us.
When we fellowship or commune with God, He lets us know when they are obvious things that need dealing with. He takes away our peace and we become aware that here is something that must change. How many Christians, I wonder, never commune or fellowship with God? I wonder how many just hold him at a distance in their lives? When you do this you can tolerate wrong things in your life – but be warned, that has spin-offs!
If we hold God at arms’ length, then we don’t fellowship with Him and if we don’t fellowship with Him it means we don’t fellowship with other believers. It is the Holy Spirit within us who enables us to fellowship heart to heart, spirit to spirit, with other believers. But on the positive side, when we do fellowship with Him and with one another, that is how His life in us is supposed to work and that is the outworking of His salvation that He wants in us. That is why John appears to ‘tack on’ this reference to the blood of Jesus, his Son, which purifies us from all sin. It is the outworking of our salvation is to be practical, not merely theoretical.
So often we seek to separate off references to our salvation and being cleansed from our sin, from practical living, but practical living is the outworking of what Jesus has achieved on the Cross. It wasn’t simply that our consciences can be cleared; it was also to enable us to live new lives and that newness involves interacting with other believers at a deep and meaningful level. If we sin and hold darkness in our lives, that prevents fellowship taking place – fellowship with God and fellowship with other believers. We will have an appearance of a Christian faith, but it will not be what God has for you, it will fall short of that. That is how significant these verses are!
