Is This The Complete Law of God's Salvation?

Luke, Chapter 10

25: And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life?

26: He said unto him, What is written in the law? how readest thou?

27: And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.

28: And he said unto him, Thou hast answered right: this do, and thou shalt live.
