1 John 2:8 (KJV) reads, "Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth."

This verse is found in the First Epistle of John, a letter believed to be written by the apostle John to encourage and instruct Christians. The verse is a continuation of John's message to the believers, emphasizing the importance of love and showing the connection between God's love and the believer's love for one another.

The verse begins with the words, "Again, a new commandment I write unto you," which refers to the commandment that Jesus gave to his disciples in John 13:34-35 (KJV) when he said, "A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another." This "new commandment" of love is emphasized by John as he writes to the believers, reminding them of the importance of loving one another as Jesus had instructed.

John goes on to say, "which thing is true in him and in you," affirming that this commandment to love one another is true in Jesus and also in the believers. This implies that Jesus demonstrated this kind of love during his earthly ministry, and now the believers are called to live out this love in their lives as well. The commandment is not just a concept, but a reality that should be evident in the lives of those who follow Christ.

John then provides the reason for this new commandment, stating, "because the darkness is past, and the true light now shineth." This phrase draws upon the imagery of light and darkness that is often used in the Bible to convey spiritual truths. In this context, "darkness" represents sin, evil, and spiritual blindness, while "light" symbolizes truth, righteousness, and the presence of God. The arrival of Jesus Christ into the world brought about a change in spiritual reality, as his light dispelled the darkness of sin and revealed God's truth and love to humanity.

The broader context of this verse is John's emphasis on the love of God and the love that believers should have for one another. Throughout his letter, John stresses the connection between knowing God and loving others, stating in 1 John 4:7-8 (KJV), "Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. He that loveth not knoweth not God; for God is love." This theme of love as a defining characteristic of God and his people ties back to Jesus's own teachings about love and unity among his followers.

Symbolically, the contrast between darkness and light in this verse represents the contrast between sin and righteousness, ignorance and truth, and the old life versus the new life in Christ. The new commandment of love represents the new way of living that comes with knowing Christ and being transformed by his love. This verse serves as a reminder to believers of the light that they have received in Christ and the love that they are called to share with one another.

In conclusion, 1 John 2:8 (KJV) holds significant meaning in the broader context of John's letter and the message of the Christian faith. It emphasizes the new commandment of love given by Jesus, the truth of this commandment in the lives of believers, and the transformative power of Christ's light that dispels the darkness of sin. This verse serves as a call to action for believers to live out the love of God in their lives and to be a reflection of the true light that now shines in Christ.
