9 If anyone claims, “I am living in the light,” but hates a fellow believer, that person is still living in darkness.
10 Anyone who loves a fellow believer is living in the light and does not cause others to stumble.
11 But 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.
12 I am writing to you who are God’s childrenbecause your sins have been forgiven through Jesus.
13 I am writing to you who are mature in the faithbecause you know Christ, who existed from the beginning.I am writing to you who are young in the faithbecause you have won your battle with the evil one.
14 I have written to you who are God’s childrenbecause you know the Father.I have written to you who are mature in the faithbecause you know Christ, who existed from the beginning.I have written to you who are young in the faithbecause you are strong.God’s word lives in your hearts,and you have won your battle with the evil one.
15 Do 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.
