"Chapter 54—To the Teachers in Our Schools My Dear Brethren and Sisters, The Lord will work in behalf of all who will walk humbly with Him. He has placed you in a position of trust. Walk carefully before Him. God's hand is on the wheel. He will guide the ship past the rocks into the haven. He will take the weak things of this world to confound the things that are mighty. 7T 267"
"But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;"
The EGW passage directly alludes to 1 Corinthians 1:27 by stating 'He will take the weak things of this world to confound the things that are mighty.' This is a clear reference to the biblical principle of God using the weak to shame the strong.
"The Lord wishes you to learn how to use the gospel net. That you may be successful in your work, the meshes of your net must be close. The application of the Scriptures must be such that the meaning shall be easily discerned. Then make the most of drawing in the net. Come right to the point. However great a man's knowledge, it is of no avail unless he is able to communicate it to others. Let the pathos of your voice, its deep feeling, make an impression on hearts. Urge your students to surrender themselves to God. “Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. And of some have compassion, making a difference: and others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.” Jude 1:21-23 . As you follow Christ's example you will have the precious reward of seeing your students won to Him. 7T 267.5"
"Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. And of some have compassion, making a difference: And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh."
Ellen White directly references Jude 1:21-23 in this passage.
