"Section 12—Closing Words “Finally, my brethren, be strong in the Lord, and in the power of His might.” Power for Service GW 505 What the church needs in these days of peril is an army of workers who, like Paul, have educated themselves for usefulness, who have a deep experience in the things of God, and who are filled with earnestness and zeal. Sanctified, self-sacrificing men are needed,—men who will not shun trial and responsibility; men who are brave and true; men in whose hearts Christ is formed “the hope of glory,” and who, with lips touched with holy fire, will “preach the word.” For want of such workers the cause of God languishes, and fatal errors, like a deadly poison, taint the morals and blight the hopes of a large part of the human race.— The Acts of the Apostles, 507 . GW 505"
"Finally, my brethren, be strong in the Lord, and in the power of his might."
The EGW passage directly quotes Ephesians 6:10, making it an explicit allusion.
"***** Those who are men in the sight of God, and who are thus recorded in the books of heaven, are those who, like Daniel, cultivate every faculty in such a way as best represents the kingdom of God to a world lying in wickedness. Progress in knowledge is essential; for when employed in the cause of God, knowledge is a power for good. The world needs men of thought, men of principle, men who are constantly growing in understanding and discernment. The press is in need of men to use it to the best advantage, that the truth may be given wings to speed it to every nation, and tongue, and people. GW 505.2"
"Children in whom was no blemish, but well favoured, and skilful in all wisdom, and cunning in knowledge, and understanding science, and such as had ability in them to stand in the king’s palace, and whom they might teach the learning and the tongue of the Chaldeans."
The EGW passage uses Daniel as an example of someone who cultivated their faculties to represent God's kingdom, which aligns with the description of Daniel and his companions in Daniel 1:4 as being skilled in wisdom and knowledge. While not a direct quote, the thematic connection is strong.
