"“Who is a wise man and endued with knowledge among you? let him show out of a good conversation his works with meekness of wisdom.” My brethren and sisters, how are you employing the gift of speech? Have you learned so to control the tongue that it shall ever obey the dictates of an enlightened conscience and holy affections? Is your conversation free from levity, pride and malice, deceit and impurity? Are you without guile before God? Words exert a telling power. Satan will, if possible, keep the tongue active in his service. Of ourselves we cannot control the unruly member. Divine grace is our only hope. 5T 175.1"
"Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom."
The EGW passage directly quotes James 3:13.
"But the tongue can no man tame; it is an unruly evil, full of deadly poison."
Both passages discuss the importance of controlling the tongue and using it for good. While EGW quotes James 3:13 earlier in the paragraph, this verse is about the untamable nature of the tongue, which is a related theme.
"Those who are eagerly studying how they may secure the pre-eminence should study rather how they may gain that wisdom which is “first pure, then peaceable, gentle, and easy to be entreated, full of mercy and good fruits, without partiality, and without hypocrisy.” I have been shown that many ministers need to have these words imprinted on the tablets of the soul. He who has Christ formed within, the hope of glory, will “show out of a good conversation his works with meekness of wisdom.” 5T 175.2"
"But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy."
EGW directly quotes James 3:17 and connects it to the idea of Christ within, making it a clear and intentional reference.
"To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:"
Both passages connect inner spiritual transformation (Christ in you, wisdom from above) with outward behavior and good works. The connection is thematic rather than a direct quote, but it's a meaningful parallel.
"Peter exhorts the believers: “Be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous: not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing. For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile: let him eschew evil, and do good; let him seek peace, and ensue it. For the eyes of the Lord are over the righteous, and His ears are open unto their prayers: but the face of the Lord is against them that do evil.” 5T 175.3"
"Finally, be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous:"
EGW directly quotes 1 Peter 3:8.
"Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing."
EGW directly quotes 1 Peter 3:9.
"For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:"
The EGW passage directly quotes 1 Peter 3:10.
"Let him eschew evil, and do good; let him seek peace, and ensue it."
The EGW passage directly quotes 1 Peter 3:11.
"For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil."
The EGW passage directly quotes 1 Peter 3:12.
