“You shall love your neighbor as yourself.” James called this the royal law (James 2:8). It is the royal teaching of King Jesus. It looks a lot like doing unto others as you would have them do unto you. It flows out of the Great Commandment. It is the high road; it is the road less traveled. This royal law is to be written on our hearts (Jeremiah 31:33), which means that it is to become a part of our very nature. We come to do it naturally by the inner training of the Spirit. The Spirit brings this royal law into our hearts (Romans 5:5). To practice the royal law of love is to show that we are a Child of the King.
