Jesus Himself teaches a much higher law than loving our neighbor’s as ourselves.
A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another. (John 13:34-35)
Jesus’ standard for disciples is NOT that we love others as we love ourselves but that we love others as He loves. What a lofty goal!
