9 Whoever says he is in the Light and [yet] hates his brother [Christian, born-again child of God his Father] is in darkness even until now.
10 Whoever loves his brother [believer] abides (lives) in the Light, and in It or in him there is no occasion for stumbling or cause for error or sin.
11 But he who hates (detests, despises) his brother [in Christ] is in darkness and walking (living) in the dark; he is straying and does not perceive or know where he is going, because the darkness has blinded his eyes.
12 I am writing to you, little children, because for His name's sake your sins are forgiven [pardoned through His name and on account of confessing His name].
13 I am writing to you, fathers, because you have come to know (recognize, be aware of, and understand) Him Who [has existed] from the beginning. I am writing to you, young men, because you have been victorious over the wicked [one]. I write to you, boys (lads), because you have come to know (recognize and be aware) of the Father.
14 I write to you, fathers, because you have come to know (recognize, be conscious of, and understand) Him Who [has existed] from the beginning. I write to you, young men, because you are strong and vigorous, and the Word of God is [always] abiding in you (in your hearts), and you have been victorious over the wicked one.
15 Do not love or cherish the world or the things that are in the world. If anyone loves the world, love for the Father is not in him.
