"His own merits, to become members of the royal family, children of the heavenly King. And the Father demonstrates His infinite love for Christ, who paid our ransom with His blood, by receiving and welcoming Christ's friends as His friends. He is satisfied with the atonement made. He is glorified by the incarnation, the life, death, and mediation of His Son. 6T 363.3"
"But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:"
Both passages discuss becoming children of God through Christ. John 1:12 speaks of becoming sons of God through belief, while EGW describes becoming members of the royal family through Christ's merits. The connection is thematic and supportive.
"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."
Both passages discuss the inheritance of believers as children of God. Romans 8:17 speaks of being heirs of God and joint-heirs with Christ, while EGW mentions becoming members of the royal family. The connection is thematic, but not a strong direct principle.
