“Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets”. - Matthew 7:12.
This principle, known as the Golden Rule, is a sound guide to achieving good neighbourliness. This rule is known as the royal law in James 2:8. No one should act from selfish or unjust motives but should put himself in the place of the other.
The love of God and of one's neighbour makes one to be impartial, and candid, and just. It prevents one from harbouring such vices as greed, envy, treachery, unkindness, slander, theft, adultery, and murder. Scripture says: “Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law”. – Romans 13:8-10
