"Many regard their own wisdom as sufficient, and they arrange things according to their judgment, thinking to bring about wonderful results. But if they would depend on God, and not on themselves, they would receive heavenly wisdom. Those who are so engrossed with their work that they cannot find time to press their way to the throne of grace and obtain counsel from God will turn the work into wrong channels. Our strength lies in our union with God through His only-begotten Son and in our union with one another. 6T 252.1"
"Trust in the Lord with all thine heart; and lean not unto thine own understanding."
The EGW passage warns against relying on one's own wisdom and encourages dependence on God, which is the core message of Proverbs 3:5. The connection is clear and directly applicable.
"The surgeon most truly successful is he who loves God, who sees God in His created work and worships Him as he traces His wise arrangement in the human organism. The most successful physician is he who fears God from his youth, as did Timothy, who feels that Christ is his constant companion, a friend with whom he can always commune. Such a physician would not exchange his position for the highest office the world could give. He is more anxious to honor God and secure His approval than to secure patronage and honor from the great men of the world. 6T 252.2"
"Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity."
EGW mentions Timothy as an example of someone who feared God from his youth. 1 Timothy 4:12 speaks to the importance of youth being an example of faith. While not a direct quote, the connection is more than superficial.
"Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,"
Both passages emphasize valuing Christ above worldly gain. EGW states the physician would not exchange his position for worldly office, while Philippians 3:8 speaks of counting all things as loss for Christ.
"Only through a sense of God's pure truth working in the mind and heart, only through the calmness and strength that He alone can impart, are they qualified to perform those critical operations which mean life or death to the afflicted ones. 6T 252.3"
"I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing."
EGW directly echoes the sentiment of John 15:5, emphasizing dependence on God for success. The phrase 'without me ye can do nothing' is directly reflected in EGW's statement 'Since without Christ we can do nothing'.
