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.

But whoever has the world’s goods (adequate resources), and sees his brother in need, but has no compassion for him, how does the love of God live in him?

By this the children of God and the children of the devil are clearly identified: anyone who does not practice righteousness [who does not seek God’s will in thought, action, and purpose] is not of God, nor is the one who does not [unselfishly] love his [believing] brother.

We know that we have passed out of death into Life, because we love the brothers and sisters. He who does not love remains in [spiritual] death.

The one who says he is in the light but still hates his fellow Christian is still in the darkness.

The one who loves his fellow Christian resides in the light, and there is no cause for stumbling in him.

But the one who hates his fellow Christian is in the darkness, walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.

Everyone who hates his fellow Christian is a murderer, and you know that no murderer has eternal life residing in him.

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.

And the commandment we have from him is this: that the one who loves God should love his fellow Christian too.

If anyone sees his fellow Christian committing a sin not resulting in death, he should ask, and God will grant life to the person who commits a sin not resulting in death. There is a sin resulting in death. I do not say that he should ask about that.

that which we have seen and heard we declare to you also, that ye also may have fellow-ship with us; and our fellowship also is with the Father, and with His Son Jesus Christ.
