"Independent men of earnest endeavor are needed, not men as impressible as putty. Those who want their work made ready to their hand, who desire a fixed amount to do and a fixed salary, and who wish to prove an exact fit without the trouble of adaptation or training, are not the men whom God calls to work in His cause. A man who cannot adapt his abilities to almost any place if necessity requires is not the man for this time. Men whom God will connect with His work are not limp and fiberless, without muscle or moral force of character. It is only by continued and persevering labor that men can be disciplined to bear a part in the work of God. These men should not become discouraged if circumstances and surroundings are the most unfavorable. They should not give up their purpose as a complete failure until they are convinced beyond a doubt that they cannot do much for the honor of God and the good of souls. 3T 496.1"
"Watch ye, stand fast in the faith, quit you like men, be strong."
Both passages emphasize the need for strength, steadfastness, and courage. EGW speaks against being "impressible as putty" and needing everything made easy, while 1 Corinthians urges believers to "quit you like men, be strong." Both passages promote the idea of being resilient and adaptable.
"but should never allow circumstances to master him. Individual independence and individual power are the qualities now needed. Individual character need not be sacrificed, but it should be modulated, refined, elevated. 3T 496.2"
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God."
The EGW passage directly addresses the principle of not conforming to the world and transforming one's character, echoing the core message of Romans 12:2.
