1 John 3:11-12 New English Translation (NET Bible)
God Is Love, So We Must Love One Another
11 For[a] this is the gospel[b] message[c] that you have heard from the beginning: that we should love one another,[d] 12 not like Cain[e] who was of the evil one and brutally[f] murdered his brother. And why did he murder him? Because his deeds were evil, but his brother’s were righteous.
