Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill. Matthew 5:17
The law given upon Sinai was the enunciation of the principle of love, a revelation to earth of the law of heaven....God had revealed the purpose of the law when He declared to Israel, "Ye shall be holy men unto Me" (Exodus 22:31)....
It is the Creator of men, the Giver of the law, who declares that it is not His purpose to set aside its precepts. Everything in nature, from the mote in the sunbeam to the worlds on high, is under law. And upon obedience to these laws the order and harmony of the natural world depend. So there are great principles of righteousness to control the life of all intelligent beings, and upon conformity to these principles the well-being of the universe depends. Before this earth was called into being, God's law existed. Angels are governed by its principles, and in order for earth to be in harmony with heaven, man also must obey the divine statues. To man in Eden Christ made known the precepts of the law "when the morning stars sang together, and all the sons of God shouted for joy" (Job 38:7). The mission of Christ on earth was not to destroy the law, but by His grace to bring man back to obedience to its precepts." (Thoughts from the Mount of Blessing, 46-48)
Reflection: True happiness and harmony in life is only to be found in following God's ways. Rebellion always brings discord and strife.
