"Jesus had come to “magnify the law, and make it honorable.” He was not to lessen its dignity, but to exalt it. The scripture says, “He shall not fail nor be discouraged, till He have set judgment in the earth.” Isaiah 42:21, 4 . He had come to free the Sabbath from those burdensome requirements that had made it a curse instead of a blessing. DA 206.1"
"He shall not fail nor be discouraged, till he have set judgment in the earth: and the isles shall wait for his law."
EGW directly quotes Isaiah 42:4 (or 42:21, 4 as written in the text) in support of her statement about Jesus magnifying the law. This is a clear and direct reference.
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil."
Both passages address the idea that Jesus came to uphold, not destroy, the law. EGW directly states Jesus came to "magnify the law, and make it honorable," while Matthew 5:17 states Jesus came to fulfill the law.
"For this reason He had chosen the Sabbath upon which to perform the act of healing at Bethesda. He could have healed the sick man as well on any other day of the week; or He might simply have cured him, without bidding him bear away his bed. But this would not have given Him the opportunity He desired. A wise purpose underlay every act of Christ's life on earth. Everything He did was important in itself and in its teaching. Among the afflicted ones at the pool He selected the worst case upon whom to exercise His healing power, and bade the man carry his bed through the city in order to publish the great work that had been wrought upon him. This would raise the question of what it was lawful to do on the Sabbath, and would open the way for Him to denounce the restrictions of the Jews in regard to the Lord's day, and to declare their traditions void. DA 206.2"
"After this there was a feast of the Jews; and Jesus went up to Jerusalem. Now there is at Jerusalem by the sheep market a pool, which is called in the Hebrew tongue Bethesda, having five porches. In these lay a great multitude of impotent folk, of blind, halt, withered, waiting for the moving of the water. For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had. And a certain man was there, which had an infirmity thirty and eight years. When Jesus saw him lie, and knew that he had been now a long time in that case, he saith unto him, Wilt thou be made whole? The impotent man answered him, Sir, I have no man, when the water is troubled, to put me into the pool: but while I am coming, another steppeth down before me. Jesus saith unto him, Rise, take up thy bed, and walk. And immediately the man was made whole, and took up his bed, and walked: and on the same day was the sabbath."
The EGW passage provides commentary and interpretation on the events described in John 5:1-9, specifically the healing at Bethesda. While not a direct quote, it expands on the narrative and explains the purpose behind Jesus' actions on the Sabbath, making it a thematic parallel.
"Jesus stated to them that the work of relieving the afflicted was in harmony with the Sabbath law. It was in harmony with the work of God's angels, who are ever descending and ascending between heaven and earth to minister to suffering humanity. Jesus declared, “My Father worketh hitherto, and I work.” All days are God's, in which to carry out His plans for the human race. If the Jews’ interpretation of the law was correct, then Jehovah was at fault, whose work has quickened and upheld every living thing since first He laid the foundations of the earth; then He who pronounced His work good, and instituted the Sabbath to commemorate its completion, must put a period to His labor, and stop the never-ending routine of the universe. DA 206.3"
"But Jesus answered them, My Father worketh hitherto, and I work."
EGW directly quotes John 5:17.
