"In happy contrast to Philip's unbelief was the childlike trust of Nathanael. He was a man of intensely earnest nature, one whose faith took hold upon unseen realities. Yet Philip was a student in the school of Christ, and the divine Teacher bore patiently with his unbelief and dullness. When the Holy Spirit was poured out upon the disciples, Philip became a teacher after the divine order. He knew whereof he spoke, and he taught with an assurance that carried conviction to the hearers. DA 293.1"
"Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!"
Both passages discuss Nathanael's character, with Jesus describing him as an Israelite 'in whom is no guile' and EGW highlighting his 'childlike trust' and earnest nature.
"While Jesus was preparing the disciples for their ordination, one who had not been summoned urged his presence among them. It was Judas Iscariot, a man who professed to be a follower of Christ. He now came forward, soliciting a place in this inner circle of disciples. With great earnestness and apparent sincerity he declared, “Master, I will follow Thee whithersoever Thou goest.” Jesus neither repulsed nor welcomed him, but uttered only the mournful words: “The foxes have holes, and the birds of the air have nests; but the Son of man hath not where to lay His head.” Matthew 8:19, 20 . Judas believed Jesus to be the Messiah; and by joining the apostles, he hoped to secure a high position in the new kingdom. This hope Jesus designed to cut off by the statement of His poverty. DA 293.2"
"And a certain scribe came, and said unto him, Master, I will follow thee whithersoever thou goest."
The EGW passage directly quotes and discusses Matthew 8:19, making it an explicit allusion. The context and interpretation are also consistent.
