"Chapter 19—Consideration in Buildings As the chosen people of God we cannot copy the habits, aims, practices, or fashions of the world. We are not left in darkness to pattern after worldly models and to depend on outward appearance for success. The Lord has told us whence comes our strength. “This is the word of the Lord unto Zerubbabel, saying, Not by might, nor by power, but by My Spirit, saith the Lord of hosts.” Zechariah 4:6 . As the Lord sees fit, He imparts to those who keep His way, power that enables them to exert a strong influence for good. On God they are dependent, and to Him they must give an account of the way in which they use the talents He has entrusted to them. They are to realize that they are God's stewards and are to seek to magnify His name. 7T 90"
"Then he answered and spake unto me, saying, This is the word of the Lord unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the Lord of hosts."
The EGW passage directly quotes Zechariah 4:6 and uses it as a foundation for her argument about relying on God's Spirit rather than worldly means.
"Those whose affections are set on God will succeed. They will lose sight of self in Christ, and worldly attractions will have no power to allure them from their allegiance. They will realize that outward display does not give strength. It is not ostentation, outward show, that gives a correct representation of the work that we, as God's chosen people, are to do. Those who are connected with our sanitarium work should be adorned with the grace of Christ. This will give them the greatest influence for good. 7T 90.2"
"Set your affection on things above, not on things on the earth."
The EGW passage directly echoes and applies the principle of setting affections on God, as stated in Colossians 3:2.
"The Lord is in earnest with us. His promises are given on condition that we faithfully do His will; therefore in the building of sanitariums He is to be made first and last and best in everything. 7T 90.3"
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you."
The EGW passage directly applies the principle of prioritizing God's will, similar to seeking first the kingdom of God in Matthew 6:33.
"Let all who are connected with the service of God be guarded, lest by desire for display they lead others into indulgence and self-glorification. God does not want any of His servants to enter into unnecessary, expensive undertakings, which bring heavy burdens of debt upon the people, thus depriving them of means that would provide facilities for the work of the Lord. So long as those who claim to believe the truth for this time walk in the way of the Lord, to do justice and judgment, they may expect that the Lord will give them prosperity. But when they choose to wander from the narrow way, they bring ruin upon themselves and upon those who look to them for guidance. 7T 90.4"
"Honour the Lord with thy substance, and with the firstfruits of all thine increase: So shall thy barns be filled with plenty, and thy presses shall burst out with new wine."
Both passages connect honoring God with resources and expecting prosperity as a result. The EGW passage warns against misusing resources, while Proverbs encourages honoring God with them.
"Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God."
Both passages emphasize doing things in a way that honors God, though the EGW passage focuses on avoiding extravagance while 1 Corinthians 10:31 is more general.
