'Fellow' in the Bible

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.

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?
