"Brother Hull, you must be guarded on every side. I saw that whatever divides the affections, or takes away from the heart supreme love for God, or prevents unlimited confidence and entire trust in Him, assumes the character and takes the form of an idol. I was pointed to the first great commandment: “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.” There is allowed no separation of our affections from God. Nothing is to divide our supreme love for Him or our delight in Him. Your will, wishes, plans, desires, and pleasures must all be in subjection. You have something to learn, to exalt the Lord God in your heart, in your conversation, in all your acts; and then Jesus can teach you, and help you, as you cast your net on the right side of the ship, to bring it to shore full of fishes. But without the help of Christ in casting your net, you may toil weeks, months, and years without seeing much fruit of your labor. 1T 436.1"
"Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind."
EGW directly quotes Matthew 22:37, making it an explicit allusion.
"Thou shalt have no other gods before me."
Both passages address the concept of prioritizing God above all else. While EGW focuses on the affections and love for God, Exodus 20:3 prohibits having other gods before Him. The underlying theme of exclusive devotion to God connects them.
"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."
Both passages discuss the idea of undivided loyalty to God, although EGW focuses on affections and the Bible verse on serving two masters. The core principle of prioritizing God is present in both.
