1). This of course is part of the Mosaic Covenant and the LORD’s design from the beginning.
a). Deuteronomy 6:4, 5 Hear, O Israel: The Lord our God is one Lord:
6:5 And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.
b). Leviticus 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the Lord.
2). Jesus stated this during His earthly ministry.
a). Matthew 22:34-40 But when the Pharisees had heard that he had put the Sadducees to silence, they were gathered together.
22:35 Then one of them, which was a lawyer, asked him a question, tempting him, and saying,
22:36 Master, which is the great commandment in the law?
22:37 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.
22:38 This is the first and great commandment.
22:39 And the second is like unto it, Thou shalt love thy neighbour as thyself.
22:40 On these two commandments hang all the law and the prophets.
