"True character is not shaped from without, and put on; it radiates from within. If we wish to direct others in the path of righteousness, the principles of righteousness must be enshrined in our own hearts. Our profession of faith may proclaim the theory of religion, but it is our practical piety that holds forth the word of truth. The consistent life, the holy conversation, the unswerving integrity, the active, benevolent spirit, the godly example, —these are the mediums through which light is conveyed to the world. DA 307.1"
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
Both passages emphasize the importance of good works and a righteous life as a means of reflecting God's light to the world.
"Jesus had not dwelt on the specifications of the law, but He did not leave His hearers to conclude that He had come to set aside its requirements. He knew that spies stood ready to seize upon every word that might be wrested to serve their purpose. He knew the prejudice that existed in the minds of many of His hearers, and He said nothing to unsettle their faith in the religion and institutions that had been committed to them through Moses. Christ Himself had given both the moral and the ceremonial law. He did not come to destroy confidence in His own instruction. It was because of His great reverence for the law and the prophets that He sought to break through the wall of traditional requirements which hemmed in the Jews. While He set aside their false interpretations of the law, He carefully guarded His disciples against yielding up the vital truths committed to the Hebrews. DA 307.2"
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil."
The EGW passage directly addresses the idea presented in Matthew 5:17, that Jesus did not come to destroy the law but to fulfill it. It explains how Jesus approached the law in his teachings.
"For had ye believed Moses, ye would have believed me: for he wrote of me."
Both passages discuss Jesus' relationship to Moses and the writings attributed to him. While not a direct quote, the EGW passage echoes the sentiment that Jesus affirmed Moses' writings.
"The Pharisees prided themselves on their obedience to the law; yet they knew so little of its principles through everyday practice that to them the Saviour's words sounded like heresy. As He swept away the rubbish under which the truth had been buried, they thought He was sweeping away the truth itself. They whispered to one another that He was making light of the law. He read their thoughts, and answered them, saying,— DA 307.3 “Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill.” Here Jesus refutes the charge of the Pharisees. His mission to the world is to vindicate the sacred claims of that law which they charge Him with breaking. If the law of God could have been changed or abrogated, then Christ need not have suffered the consequences of our transgression. He came to explain the relation of the law to man, and to illustrate its precepts by His own life of obedience. DA 307.4"
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil."
The EGW passage directly quotes Matthew 5:17 and provides commentary on it.
