"I saw that Satan watches the peculiar, selfish, covetous temperament of some who profess the truth, and he will tempt them by throwing prosperity in their path, offering them the riches of earth. He knows that if they do not overcome their natural temperament, they will stumble and fall by loving mammon, worshiping their idol. Satan's object is often accomplished. The strong love of the world overcomes, or swallows up, the love of the truth. The kingdoms of the world are offered them, and they eagerly grasp their treasure and think they are wonderfully prospered. Satan triumphs because his plan has succeeded. They have given up the love of God for the love of the world. 1T 142.1"
"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 of not being able to serve both God and mammon, as stated in Matthew 6:24. The concept of loving the world over God is central to both passages.
"Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; And saith unto him, All these things will I give thee, if thou wilt fall down and worship me."
Both passages describe Satan offering worldly kingdoms/riches in exchange for allegiance/worship. The EGW passage expands on this theme by describing how Satan tempts believers with prosperity, mirroring the temptation of Christ in Matthew 4:8-9.
"I saw that the brethren who have possessions have a work to do to tear away from these earthly treasures and to overcome their love of the world. Many of them love this world, love their treasure, but are not willing to see it. They must be zealous and repent of their selfish covetousness, that the love of the truth may swallow up everything else. I saw that many of those who have riches will fail to buy the gold, white raiment, and eyesalve. Their zeal does not possess intensity and earnestness proportionate to the value of the object of which they are in pursuit. 1T 142.4"
"For where your treasure is, there will your heart be also."
The EGW passage directly echoes the sentiment of Matthew 6:21, focusing on the connection between treasure and the heart/affections. The reference to 'gold, white raiment, and eyesalve' alludes to Revelation 3:18, but the core concept aligns with Matthew 6:21.
