"This is the knowledge needed by all who are working for the uplifting of their fellow men. Transformation of character, purity of life, efficiency in service, adherence to correct principles, all depend upon a right knowledge of God. This knowledge is the essential preparation both for this life and for the life to come. MH 409.3 “The knowledge of the Holy is understanding.” Proverbs 9:10 . MH 409.4"
"The fear of the Lord is the beginning of wisdom: and the knowledge of the holy is understanding."
The EGW passage directly quotes Proverbs 9:10, making it a clear and explicit allusion.
"And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent."
EGW directly quotes Proverbs 9:10 in the passage.
"According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:"
Both passages emphasize the importance of knowledge of God for life and godliness/uplifting fellow men. While not a direct quote, the thematic connection is present.
