If we say we have fellowship with him while we walk in darkness, we lie and do not practice 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 cleanses us from all sin. If we say 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. If we say we have not sinned, we make him a liar, and his word is not in us. -1 John 1:6-10 ESV
At first glance, it seems that there is almost a contradiction. John is telling us that we shouldn’t walk in the darkness and say that we are in the light because if we do, we make ourselves liars and the truth is not in us. However, if we say we’ve not sinned, we make God a liar and His Word isn’t in us. Most of our modern interpretations of this passage imply that when we ‘walk in the light’ we never sin, but for those of us that are realistic, we know sometimes we slip and fall.
Walking in the light is our sanctification. It is a continual process of repentance and growing in love and grace as the Holy Spirit empowers are lives for service in the Lord’s work.
This is why John tells us that He is faithful and just to forgive us of our sins. Jesus knows that imperfect human beings are incapable of being perfect. William Barclay offers some insight into what John means here.
“John is laying down the blunt truth that the man who says one thing with his lips and another thing with his life is a liar. He is not thinking of the man who tries his hardest and yet often fails. “A man,” said H. G. Wells, “may be a very bad musician, and may yet be passionately in love with music”; and a man may be very conscious of his failures and yet be passionately in love with Christ and the way of Christ. John is thinking of the man who makes the highest possible claims to knowledge, to intellectual eminence and to spirituality, and who yet allows himself things which he well knows are forbidden. The man who professes to love Christ and deliberately disobeys him, is guilty of a lie.” – William Barclay
As we have fellowship with Him, it strengthens and empowers our fellowship with others. Sin is antisocial. It separates us from God and as a result, separates us from others. Let’s walk in repentance and fellowship and be ever fighting in the war against sin in our lives.
