"“If thou put the brethren in remembrance of these things, thou shalt be a good minister of Jesus Christ.” The Danger of Rejecting Light God intends that, even in this life, truth shall be ever unfolding to His people. There is only one way in which this knowledge can be obtained. We can attain to an understanding of God's word only through the illumination of that Spirit by which the Word was given. “The things of God knoweth no man, but the Spirit of God;” “for the Spirit searcheth all things, yea, the deep things of God.” [ 1 Corinthians 2:11, 10 .] And the Saviour's promise to His followers was, “When He, the Spirit of truth, is come, He will guide you into all truth.... For He shall receive of Mine, and shall show it unto you.” [ John 16:13, 14 .]... GW 297"
"If thou put the brethren in remembrance of these things, thou shalt be a good minister of Jesus Christ, nourished up in the words of faith and of good doctrine, whereunto thou hast attained."
The EGW passage directly quotes 1 Timothy 4:6 and builds upon it.
"But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God."
The EGW passage directly quotes 1 Corinthians 2:10 and builds upon it.
"Peter exhorts his brethren to “grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ.” [ 2 Peter 3:18 .] Whenever the people of God are growing in grace, they will be constantly obtaining a clearer understanding of His word. They will discern new light and beauty in its sacred truths. This has been true in the history of the church in all ages, and thus it will continue to the end. But as real spiritual life declines, it has ever been the tendency to cease to advance in the knowledge of the truth. Men rest satisfied with the light already received from God's word, and discourage any further investigation of the Scriptures. They become conservative, and seek to avoid discussion. GW 297.2"
"But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and for ever. Amen."
EGW directly quotes 2 Peter 3:18 and builds her argument upon it.
"But the path of the just is as the shining light, that shineth more and more unto the perfect day."
While not a direct quote, the idea of increasing light and understanding in Proverbs 4:18 aligns with EGW's statement about growing in grace and understanding God's word.
