"We need to guard continually against those books which contain sophistry in regard to geology and other branches of science. Before the theories of men of science are presented to immature students, they need to be carefully sifted from every trace of infidel suggestions. One tiny seed of infidelity sown by a teacher in the heart of a student may spring up and bring forth a harvest of unbelief. The sophistries regarding God and nature that are flooding the world with skepticism are the inspiration of the fallen foe. Satan is a Bible student. He knows the truths that are essential for salvation, and it is his study to divert minds from these truths. Let our teachers beware lest they echo the falsehoods of the enemy of God and man. CT 390.1"
"O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:"
Both passages warn against the dangers of 'science falsely so called' or 'sophistry in regard to geology and other branches of science.' They both caution against being led astray by false teachings that contradict true faith.
"When any one heareth the word of the kingdom, and understandeth it not, then cometh the wicked one, and catcheth away that which was sown in his heart. This is he which received seed by the way side."
Both passages use the imagery of seeds being sown in the heart/mind. Matthew 13:19 describes how the wicked one snatches away the word sown in the heart, while EGW describes how a seed of infidelity can spring up and bring forth a harvest of unbelief. The connection is in the shared metaphor of sowing seeds of belief/unbelief.
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life."
Both passages speak of something 'from heaven' that sustains spiritual life. While not a direct quote, the thematic connection is strong.
"And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst."
Both passages refer to something that satisfies a spiritual need. John 6:35 speaks of Jesus as the bread of life, and the EGW quote speaks of something from heaven that sustains spiritual life. The connection is thematic.
