"As the preaching of Jonah was a sign to the Ninevites, so Christ's preaching was a sign to His generation. But what a contrast in the reception of the word! Yet in the face of indifference and scorn the Saviour labored on and on, until He had accomplished His mission. PK 274.1"
"But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:"
EGW draws a direct comparison between Jonah's preaching as a sign and Christ's preaching as a sign, referencing the concept presented in Matthew 12:39. This is more than a general theme; it's a specific typological connection being made.
"The lesson is for God's messengers today, when the cities of the nations are as verily in need of a knowledge of the attributes and purposes of the true God as were the Ninevites of old. Christ's ambassadors are to point men to the nobler world, which has largely been lost sight of. According to the teaching of the Holy Scriptures, the only city that will endure is the city whose builder and maker is God. With the eye of faith man may behold the threshold of heaven, flushed with God's living glory. Through His ministering servants the Lord Jesus is calling upon men to strive with sanctified ambition to secure the immortal inheritance. He urges them to lay up treasure beside the throne of God. PK 274.2"
"For he looked for a city which hath foundations, whose builder and maker is God."
EGW directly references the concept of the city whose builder and maker is God, which is a clear allusion to Hebrews 11:10.
