"None should allow their own work to excuse neglect of the Lord's sacred service. Much better might they lay aside the work which concerns themselves than neglect their duty to God. 7T 188.2"
"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."
The EGW passage directly echoes the principle in Matthew 6:24 about prioritizing God's service over personal work, reflecting the idea that one cannot serve two masters.
