"In this letter Paul gave free expression to his burden in behalf of the Jews. Ever since his conversion, he had longed to help his Jewish brethren to gain a clear understanding of the gospel message. “My heart's desire and prayer to God for Israel is,” he declared, “that they might be saved.” AA 374.1"
"Brethren, my heart’s desire and prayer to God for Israel is, that they might be saved."
The EGW passage directly quotes Romans 10:1, making it an explicit allusion.
"I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost, That I have great heaviness and continual sorrow in my heart. For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh: Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises; Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen."
The EGW passage directly quotes Romans 9:1-5, specifically mentioning Paul's desire for the salvation of Israel. This is more than a thematic parallel; it's a direct reference and amplification of Paul's sentiments.
"and of whom as concerning the flesh Christ came, who is over all, God blessed forever.” AA 374.2"
"Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen."
This is a direct quote from Romans 9:5. The connection is undeniable.
