"These things do not belong alone to Battle Creek. I am grieved at the selfishness among professed Sabbathkeepers everywhere. Christ has gone to prepare eternal mansions for us, and shall we refuse Him a home for only a few days, in the person of His saints who are cast out? He left His home in glory, His majesty and high command, to save lost man. He became poor that we through His poverty might become rich. He submitted to insult, that man might be exalted, and provided a home that would be matchless for loveliness, and enduring as the throne of God. Those who finally overcome and sit down with Christ upon His throne will follow the example of Jesus, and from a willing, happy choice will sacrifice for Him in the person of His saints. Those who cannot do this from choice will go away into everlasting punishment. 1T 680.1"
"For ye know the grace of our Lord Jesus Christ, that, though he was rich, yet for your sakes he became poor, that ye through his poverty might be rich."
The EGW passage directly references and expands upon the concept of Christ's poverty leading to our riches, as described in 2 Corinthians 8:9. It's more than a thematic parallel; it's a direct allusion.
