1 John 4:20-21
4:20 If anyone says “I love God” and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.
4:21 And the commandment we have from him is this: that the one who loves God should love his fellow Christian too.
1 John 2:10
2:10 The one who loves his fellow Christian
resides in the light, and there is no cause for stumbling in him.
1 John 3:10-23
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.
3:19 And by this we will know that we are of the truth and will convince our conscience in his presence,
3:20 that if our conscience condemns us, that God is greater than our conscience and knows all things.
3:21 Dear friends, if our conscience does not condemn us, we have confidence in the presence of God,
3:22 and whatever we ask we receive from him, because we keep his commandments and do the things that are pleasing to him.
3:23 Now this is his commandment: that we believe in the name of his Son Jesus Christ and love one another, just as he gave us the commandment.
1 John 5:1
5:1 Everyone who believes that Jesus is the Christ
has been fathered
by God, and everyone who loves the father
loves the child fathered by him.
