"In the school of Christ, students are never graduated. Among the pupils are both old and young. Those who give heed to the instructions of the divine Teacher constantly advance in wisdom, refinement, and nobility of soul, and thus they are prepared to enter that higher school where advancement will continue throughout eternity.

"Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls."
While not a direct quote, the concept of continuous learning from Christ in the EGW passage aligns with the idea of taking Christ's yoke and learning from Him, as mentioned in Matthew 11:29. The EGW passage expands on the lifelong nature of this learning.
"It is in this world, amid its trials and temptations, that we are to gain a fitness for the society of the pure and holy. Those who become so absorbed in less important studies that they cease to learn in the school of Christ are meeting with infinite loss. They insult the divine Teacher by the rejection of the provisions of His grace. The longer they continue in their course, the more hardened they are in sin. Their retribution will be proportioned to the infinite value of the blessings they have spurned. CT 51.3"
"For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?"
Both passages address the concept of infinite loss versus eternal gain. The EGW passage speaks of those who become absorbed in less important studies meeting with 'infinite loss,' while Matthew 16:26 asks what profit there is in gaining the whole world but losing one's soul. The 'less important studies' are analogous to gaining the world, and the 'infinite loss' is analogous to losing one's soul.
"Follow peace with all men, and holiness, without which no man shall see the Lord:"
Both passages emphasize the importance of holiness and preparation for a future with God. The EGW passage speaks of gaining 'fitness for the society of the pure and holy,' while Hebrews 12:14 states that 'without holiness no man shall see the Lord.' The idea of rejecting the 'school of Christ' and the 'provisions of His grace' is directly related to failing to follow peace and holiness.
"every debasing, groveling vice, and raising the thoughts and desires toward God and heaven. Linked to the Infinite One, man is made partaker of the divine nature. Upon him the shafts of evil have no effect; for he is clothed with the panoply of Christ's righteousness. CT 51.4"
"Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust."
Both passages discuss partaking of the divine nature. The EGW passage speaks of being linked to the Infinite One and partaking of the divine nature, while 2 Peter 1:4 speaks of becoming partakers of the divine nature through God's promises. The thematic connection is strong.
