"“Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.” 1 Corinthians 2:6-13 . AA 251.1"
"Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God."
The EGW passage directly quotes 1 Corinthians 2:12.
"Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought: But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory: Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory. But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual."
Ellen White directly references 1 Corinthians 2:6-13 in this passage.
"Paul realized that his sufficiency was not in himself, but in the presence of the Holy Spirit, whose gracious influence filled his heart, bringing every thought into subjection to Christ. He spoke of himself as “always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body.” 2 Corinthians 4:10 . In the apostle's teachings Christ was the central figure. “I live,” he declared, “yet not I, but Christ liveth in me.” Galatians 2:20 . Self was hidden; Christ was revealed and exalted. AA 251.2"
"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."
The EGW passage directly quotes Galatians 2:20.
"Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body."
Ellen White directly references 2 Corinthians 4:10 in this passage.
"Paul was an eloquent speaker. Before his conversion he had often sought to impress his hearers by flights of oratory. But now he set all this aside. Instead of indulging in poetic descriptions and fanciful representations, which might please the senses and feed the imagination, but which would not touch the daily experience, Paul sought by the use of simple language to bring home to the heart the truths that are of vital importance. Fanciful representations of truth may cause an ecstasy of feeling, but all too often truths presented in this way do not supply the food necessary to strengthen and fortify the believer for the battles of life. The immediate needs, the present trials, of struggling souls—these must be met with sound, practical instruction in the fundamental principles of Christianity. AA 251.3"
"And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power:"
Both passages contrast worldly wisdom/enticements with the Spirit's power and simple language. EGW expands on the idea of avoiding 'enticing words' and focusing on practical instruction.
"Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual."
Both passages contrast human wisdom with the Holy Spirit's teaching. EGW elaborates on this by contrasting 'poetic descriptions' with 'sound, practical instruction'.
