"Even these words fail of expressing the greatness and the glory of God's purpose to be accomplished through His people. Not to this world only but to the universe are we to make manifest the principles of His kingdom. The apostle Paul, writing by the Holy Spirit, says: “Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; and to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: to the intent that now unto the principalities and powers in heavenly places might be [made] known by the church the manifold wisdom of God.” Ephesians 3:8-10 . 6T 13.1"
"Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:"
The EGW passage directly quotes Ephesians 3:8-10 and builds upon the idea that the church is meant to reveal God's wisdom to the universe.
"Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,"
Ellen White directly references Ephesians 3:8-10 in this passage.
"Brethren, “we are made a spectacle unto the world, and to angels, and to men.” “What manner of persons ought ye to be in all holy conversation and godliness, looking for and hasting the coming of the day of God?” 1 Corinthians 4:9 ; 2 Peter 3:11, 12 , margin. 6T 13.2"
"Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,"
EGW directly quotes 2 Peter 3:11.
"For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men."
EGW directly quotes 1 Corinthians 4:9.
