Meaning in one sentence

The commandment to love is both old and new. John explains why it is true in Christ and in believers because darkness fades and light shines.

I John New Testament Greek

Context

John has been calling his readers to walk in the light as God is light. He reminds them that anyone who claims to know God but does not keep His commandments is living a lie. In the verses just before this one, he says the commandment he writes is not new but old, the word they have heard from the beginning. That older command is the call to love one another. But then he pivots. He calls it a new commandment too. He is not contradicting himself. Jesus had said the same thing at the Last Supper: love one another as I have loved you. That made the old command new, because Christ gave it a fresh meaning and a fresh power. And now John says this newness is true both in Christ Himself and in his readers, because the darkness of the old age is passing away and the true light of Christ is already shining.

Key Words

Three words in this verse carry the weight. The word for new in Greek is kainos, not neos. Neos means recent in time. Kainos means fresh in quality, something never seen before. This commandment is not just recently given; it has a new character because it flows from the life of Christ and the power of the Spirit.

The word for darkness is skotia. In John’s Gospel it often means moral blindness, the ignorance of God that keeps people from love. It is not just an absence of light; it is an active state of stumbling.

Then the verb for is passing away (paragetai) is present tense. It is happening now but not yet finished. The same tense appears for the light that shines (phainei). The darkness is still going, but the true light is already here. That present reality changes how we live today.

How Christians Read This Verse

Many Christians across traditions have noted how the command to love can be both old and new. Some point out that it was old because God gave it from the beginning of His covenant people, but new because Christ renewed it through His own example and sacrifice. Others, like John Calvin, focused on the enduring nature of the command: it never grows old, so believers must keep practicing it throughout their whole life. Still others see the newness in the contrast between the old age of the law and the new age of the gospel where love is powered by the presence of Christ. All agree that the commandment finds its truth in Christ first, and then in those who follow Him.

A common misunderstanding

A common misreading of this verse is to think the darkness has already completely disappeared. If darkness is fully gone, then why do we still struggle with sin and hatred? John uses the present tense: the darkness is passing away, not has passed. The process is real and certain, but not finished. That keeps us humble and dependent on the light that is already here.

Living This Out

This verse asks you to see the command to love in a new way. It is not just a rule you try harder to keep. It is something that becomes true in you because it is already true in Christ. The next time you face a relationship that feels dead or a grudge that seems stuck, remember that the darkness of that bitterness is passing away. It does not have the final word. The true light is already shining, not far off, but in Christ, and by His Spirit, in you. You can love because that light is real right now, and it is stronger than the fading dark.

Main takeaway: The command to love is forever new because Christ's true light is already shining, and His love becomes true in us as darkness fades.

For Families

For ages 5, 8

God tells us to love each other. Jesus made this command new by showing us His love. The darkness of wrong things is going away, and Jesus' light is already shining in our hearts.

For ages 9, 12

John says the command to love is both old and new. It's old because God has always wanted His people to love each other. But Jesus made it new by showing the perfect example of love, like when He washed His disciples' feet and died for us. Now, when we follow Jesus, His love becomes real in us. The darkness of selfishness is fading, and the light of Christ is already shining. We can love others even when it's hard, because the light is stronger than the dark.

Questions People Ask

Why does John say the commandment is both old and new?

John calls it old because his readers had heard it from the beginning of their Christian life. He calls it new because Christ renewed it through His own example and by the power of the Spirit. It is the same command to love, but in Christ it takes on a fresh meaning and a new strength.

What does it mean that the commandment is 'true in him and in you'?

It means the commandment is first fully realized and lived out in Christ Jesus. He perfectly loved the Father and others. Then it becomes true in believers as they walk in that same love. The commandment is not just a written rule; it is a reality that takes shape in Jesus and then in those who follow Him.

What does 'the darkness is passing away' mean?

Darkness in John's letters often means moral blindness, ignorance of God, and the power of sin. Saying it 'is passing away' uses a present tense verb, meaning the process is happening now but not yet complete. The old age of sin and death is giving way to the new age of light in Christ, but we still live in the overlap.

What is the 'true light' that already shines?

The true light is Jesus Christ Himself, who reveals God fully and brings salvation. John calls it 'true' to contrast it with anything that only claims to be light. It already shines, meaning the light of Christ is present now, not just in the future. Believers live under its brightness even while the darkness still fades.
