A profession of Christianity without corresponding faith and works will avail nothing. No man can serve two masters. The children of the wicked one are their own master's servants; to whom they yield themselves servants to obey, his servants they are, and they cannot be the servants of God until they renounce the devil and all his works. It cannot be harmless for servants of the heavenly King to engage in the pleasures and amusements which Satan's servants engage in, even though they often repeat that such amusements are harmless. God has revealed sacred and holy truths to separate His people from the ungodly and purify them unto Himself. Seventh-day Adventists should live out their faith. Those who obey the Ten Commandments view the state of the world and religious things from a standpoint altogether different from that of professors who are lovers of pleasure, who shun the cross, and live in violation of the fourth commandment.

"No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon."
EGW directly quotes and expands upon the concept of serving two masters, making it an explicit allusion.
"Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?"
EGW's statement about being servants to whom we obey directly reflects the principle outlined in Romans 6:16.
"Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?"
The EGW passage discusses separation from the world and serving only one master (God), which aligns with the principle of not being unequally yoked with unbelievers as described in 2 Corinthians 6:14. The idea of not being able to serve two masters is also a direct allusion to Matthew 6:24.
"Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven."
The statement that a profession of Christianity without corresponding faith and works will avail nothing is a direct reflection of the principle that it is not enough to simply say 'Lord, Lord,' but to do the will of the Father.
