"Angels were represented to me as looking on with intense interest to mark the appearance of the weary yet faithful watchers, lest they be too sorely tried, and sink under the toil and hardships made doubly severe because their brethren had been diverted from their watch, and become drunk with worldly cares and beguiled by worldly prosperity. These heavenly angels grieved that those who were once watching should, by their indolence and unfaithfulness, increase the trial and burdens of those who were earnestly and perseveringly endeavoring to maintain their waiting, watching position. 2T 193.1"
"Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?"
The EGW passage describes angels watching and ministering to believers, which aligns with the general concept of Hebrews 1:14 about angels being ministering spirits. However, the connection is not a direct quote or explicit allusion, but rather a thematic parallel.
I saw that it was impossible to have the affections and interests engrossed in worldly cares, to be increasing earthly possessions, and yet be in a waiting, watching position, as our Saviour has commanded. Said the angel: “They can secure but one world. In order to acquire the heavenly treasure, they must sacrifice the earthly. They cannot have both worlds.” I saw how necessary a continuance of faithfulness in watching was in order to escape the delusive snares of Satan. He leads those who should be waiting and watching, to take an advance step toward the world; they have no intention of going further, but that one step removed them that much further from Jesus, and made it easier to take the next; and thus step after step is taken toward the world, until all the difference between them and the world is a profession, a name only. They have lost their peculiar, holy character, and there is nothing except their profession to distinguish them from the lovers of the world around them. 2T 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 Matthew 6:24, stating the impossibility of serving both worldly and heavenly interests. The phrase "They cannot have both worlds" is a clear application of the "no man can serve two masters" principle.
