1 John 3:10-18

3:10 By this the children of God and the children of the devil are revealed: Everyone who does not practice righteousness – the one who does not love his fellow Christian – is not of God.

God Is Love, So We Must Love One Another

3:11 For this is the gospel message that you have heard from the beginning: that we should love one another, 3:12 not like Cain who was of the evil one and brutally murdered his brother. And why did he murder him? Because his deeds were evil, but his brother’s were righteous.

3:13 Therefore do not be surprised, brothers and sisters, if the world hates you. 3:14 We know that we have crossed over from death to life because we love our fellow Christians. The one who does not love remains in death. 3:15 Everyone who hates his fellow Christian is a murderer, and you know that no murderer has eternal life residing in him. 3:16 We have come to know love by this: that Jesus laid down his life for us; thus we ought to lay down our lives for our fellow Christians. 3:17 But whoever has the world’s possessions and sees his fellow Christian in need and shuts off his compassion against him, how can the love of God reside in such a person?

3:18 Little children, let us not love with word or with tongue but in deed and truth.
