Firm Principle: The Great Commandment
Then one of them, which was a lawyer, asked him a question, tempting him, and saying.
Master, what is the great commandment in the law?
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 a second is like unto it, Thou shalt love thy neighbor as thyself.
On these two commandments hang all the law and the prophets.
— Matthew 22:35-40
