The Sum of All?

Can it be true?  One sentence is the sum, the absolute total, of the whole of God’s expansive revelation to man?

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

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

For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.  Galatians 5:14

It must be true because God has said exactly that three times. And He has said it in other ways.

Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.  This is the first and great commandment.  And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.  Matthew 22:37-40

And He expands upon it.

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

The truth God gives concerning love for others is extensive.  And they are commands to be followed.  

May I ask a question?  What would life be like if we truly obeyed, with our whole beings, these principles?  I am sure I do not know the answer.  

May God mercifully help us to, by His grace and strengthening, to have the love of Christ for one another.
