"Chapter 18—The Education Most Essential For Gospel Workers There are Christian workers who have not received a collegiate education because it was impossible for them to secure this advantage; but God has given evidence that he has chosen them. He has ordained them to go forth and labor in his vineyard. He has made them effectual co-workers with himself. They have a teachable spirit; they feel their dependence upon God, and the Holy Spirit is with them to help their infirmities. It will quicken and energize the mind, direct their thoughts, and aid in the presentation of truth. When the laborer stands before the people to hold forth the words of life, there is heard in his voice the echo of the voice of Christ. CE 141"
"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;"
Both passages highlight God's choice of those who may not have worldly advantages but are effective in His service due to their teachable spirit and the Holy Spirit's guidance.
