8Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining. 9Anyone who claims to be in the light but hates a brother or sister The Greek word for brother or sister (adelphos) refers here to a believer, whether man or woman, as part of God’s family; also in verse 11; and in 3:15, 17; 4:20; 5:16. is still in the darkness. 10Anyone who loves their brother and sister The Greek word for brother and sister (adelphos) refers here to a believer, whether man or woman, as part of God’s family; also in 3:10; 4:20, 21. lives in the light, and there is nothing in them to make them stumble.
11But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.
