"1 John 2:5, 6 : “But whoso keepeth His word, in him verily is the love of God perfected: hereby know we that we are in Him. He that saith he abideth in Him ought himself also so to walk, even as He walked.” 1T 286.1 1 Peter 2:9 : “But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of Him who hath called you out of darkness into His marvelous light.” 1T 286.2"
"But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:"
Ellen White directly references 1 Peter 2:9 in this passage.
"The Son of God was the heir of all things, and the dominion and glory of the kingdoms of this world were promised to Him. Yet when He appeared in this world, it was without riches or splendor. The world understood not His union with the Father; the excellency and glory of His divine character were hid from them. He was therefore “despised and rejected of men,” and “we did esteem Him stricken, smitten of God, and afflicted.” Even as Christ was in the world, so are His followers. They are the sons of God, and joint heirs with Christ; and the kingdom and dominion belong to them. The world understand not their character and holy calling; they perceive not their adoption into the family of God. Their union and fellowship with the Father and Son is not manifest, and while the world behold their humiliation and reproach, it does not appear what they are, or what they shall be. They are strangers. The world know them not, and appreciate not the motives which actuate them. 1T 286.4"
"He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not."
EGW directly quotes Isaiah 53:3 in this passage, making it an explicit allusion.
"And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together."
EGW's statement about believers being "joint heirs with Christ" directly echoes the concept presented in Romans 8:17. The context of suffering and glorification is also present, strengthening the connection.
