"It was to Christ that the prophetic promise was given: “Thus saith the Lord, the Redeemer of Israel, and His Holy One, to Him whom man despiseth, to Him whom the nation abhorreth, ... thus saith the Lord, ... I will preserve Thee, and give Thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages; that Thou mayest say to the prisoners, Go forth; to them that are in darkness, Show yourselves.... They shall not hunger nor thirst; neither shall the heat nor sun smite them: for He that hath mercy on them shall lead them, even by the springs of water shall He guide them.” Isaiah 49:7-10 . PK 689.1"
"Thus saith the Lord, the Redeemer of Israel, and his Holy One, to him whom man despiseth, to him whom the nation abhorreth, to a servant of rulers, Kings shall see and arise, princes also shall worship, because of the Lord that is faithful, and the Holy One of Israel, and he shall choose thee. Thus saith the Lord, In an acceptable time have I heard thee, and in a day of salvation have I helped thee: and I will preserve thee, and give thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages; That thou mayest say to the prisoners, Go forth; to them that are in darkness, Shew yourselves. They shall feed in the ways, and their pastures shall be in all high places. They shall not hunger nor thirst; neither shall the heat nor sun smite them: for he that hath mercy on them shall lead them, even by the springs of water shall he guide them."
Ellen White directly references Isaiah 49:7-10 in this passage.
"The steadfast among the Jewish nation, descendants of that holy line through whom a knowledge of God had been preserved, strengthened their faith by dwelling on these and similar passages. With exceeding joy they read how the Lord would anoint One “to preach good tidings unto the meek,” “to bind up the brokenhearted, to proclaim liberty to the captives,” and to declare “the acceptable year of the Lord.” Isaiah 61:1, 2 . Yet their hearts were filled with sadness as they thought of the sufferings He must endure in order to fulfill the divine purpose. With deep humiliation of soul they traced the words in the prophetic roll: PK 689.2"
"The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,"
EGW directly quotes Isaiah 61:1, 2, which is the basis for Luke 4:18. The connection is undeniable.
