1 John 2:7

5 But if anyone keeps His word, the love of God has been truly perfected in him. By this we know that we are in Him:

6 Whoever claims to abide in Him must walk as Jesus walked.

Beloved, I am not writing to you a new commandment, but an old one, which you have had from the beginning. This commandment is the message you have heard.

8 Then again, I am also writing to you a new commandment, which is true in Him and also in you. For the darkness is fading and the true light is already shining.

9 If anyone claims to be in the light but hates his brother, he is still in the darkness.

Do read the surrounding verses too, because the context often says more than a single verse.
