1 John 2:8b-11, the Inclusive Translation:

What I am writing to you is indeed a new commandment. Its truth is seen in Christ and in you, because the night is passing and the true light is already shining. Those who claim to be in the light but hate their neighbors are still in the dark. But those who love their neighbors are living in the light and need not be afraid of stumbling. Those who hate their neighbors are in the darkness and do not know where they are going, because the darkness has blinded them.
