1 John 2:3–17

³And we can be sure that we know him if we obey his commandments. ⁴If someone claims, “I know God,” but doesn’t obey God’s commandments, that person is a liar and is not living in the truth. ⁵But those who obey God’s word truly show how completely they love him. That is how we know we are living in him. ⁶Those who say they live in God should live their lives as Jesus did.

A New Commandment

⁷Dear friends, I am not writing a new commandment for you; rather it is an old one you have had from the very beginning. This old commandment—to love one another—is the same message you heard before. ⁸Yet it is also new. Jesus lived the truth of this commandment, and you also are living it. For the darkness is disappearing, and the true light is already shining.

⁹If anyone claims, “I am living in the light,” but hates a fellow believer, that person is still living in darkness. ¹⁰Anyone who loves a fellow believer is living in the light and does not cause others to stumble. ¹¹But anyone who hates a fellow believer is still living and walking in darkness. Such a person does not know the way to go, having been blinded by the darkness.

¹²I am writing to you who are God’s children

because your sins have been forgiven through Jesus.

¹³I am writing to you who are mature in the faith

because you know Christ, who existed from the beginning.

I am writing to you who are young in the faith

because you have won your battle with the evil one.

¹⁴I have written to you who are God’s children

because you know the Father.

I have written to you who are mature in the faith

because you know Christ, who existed from the beginning.

I have written to you who are young in the faith

because you are strong.

God’s word lives in your hearts,

and you have won your battle with the evil one.

Do Not Love This World

¹⁵Do not love this world nor the things it offers you, for when you love the world, you do not have the love of the Father in you. ¹⁶For the world offers only a craving for physical pleasure, a craving for everything we see, and pride in our achievements and possessions. These are not from the Father, but are from this world. ¹⁷And this world is fading away, along with everything that people crave. But anyone who does what pleases God will live forever.
