The apostolic writers know how the believers are encumbered by their own sins, and how they sometimes lose heart or even despair. But the Light of Christ which reveals our sins leads to confession, forgiveness and sanctification!
Pay close attention to how the Apostle John draws the attention of sin-troubled believers toward the eternal, spiritual and righteous beauty of Christ. He does not give sin-troubled believers an exposition of the Law which condemns them, but he strikes hope into their hearts by preaching the living, saving and sanctifying glory of the Son of God:
The Incarnation of the Word of Life (1 John 1, NIV) My comments are in square brackets.
1 1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched—this we proclaim concerning the Word of life. 2 The life appeared; we have seen it and testify to it, and we proclaim to you the eternal life, which was with the Father and has appeared to us. 3 We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ. 4 We write this to make our joy complete.
Then John writes to show that the most beautiful and living One is the most righteous One who can communicate his own righteousness to us.
Light and Darkness, Sin and Forgiveness
5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. 6 If we claim to have fellowship with him and yet walk in the darkness [not in the Light of Christ, uncaring of our sin], we lie and do not live out the truth. 7 But if we walk in the light [exposing our sin], as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, [continually] purifies us from all sin.
8 If we claim to be without sin, we deceive ourselves and the truth [of the gospel] is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
John preaches the way of life to those who believe in Jesus and who, by his light, see not only his righteousness, but also their own sins, and they are built up in him through faith, confession of sin and love of Christ and God the Father, to become full of the righteousness of Christ in eternal life. Those who reject the light and walk in darkness, careless of their sins, have no cleansing and prove that the saving and regenerating word of God does not shine within them.
