"Says the True Witness: “I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spew thee out of My mouth.” Satan is willing that you should be Christians in name, for you can suit his purpose better. If you have a form and not true godliness, he can use you to decoy others into the same self-deceived way. Some poor souls will look to you, instead of looking to the Bible standard, and will come up no higher. They are as good as you, and are satisfied. 1T 162.1"
"I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot."
EGW directly quotes Revelation 3:15.
"The young are often urged to do duty, to speak or pray in meeting; urged to die to pride. Every step they are urged. Such religion is worth nothing. Let the carnal heart be changed, and it will not be such drudgery, ye coldhearted professors, to serve God. All that love of dress and pride of appearance will be gone. The time that you spend standing before the glass preparing the hair to please the eye, should be devoted to prayer and searching of heart. There will be no place for outward adornment in the sanctified heart; but there will be an earnest, anxious seeking for the inward adorning, the Christian graces—the fruits of the Spirit of God. 1T 162.2"
"Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;"
EGW directly addresses the issue of outward adornment versus inward character, echoing the sentiment and topic of 1 Peter 3:3.
"But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly."
Both passages encourage private devotion and discourage outward show. However, the connection is not strong enough to be considered a direct allusion or principle.
"Says the apostle: “Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel; but let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.” 1T 162.3"
"Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;"
EGW directly quotes 1 Peter 3:3.
"Subdue the carnal mind, reform the life, and the poor mortal frame will not be so idolized. If the heart is reformed, it will be seen in the outward appearance. If Christ be in us the hope of glory, we shall discover such matchless charms in Him that the soul will be enamored. It will cleave to Him, choose to love Him, and in admiration of Him, self will be forgotten. Jesus will be magnified and adored, and self abased and humbled. But a profession, without this deep love, is mere talk, dry formality, and heavy drudgery. Many of you may retain a notion of religion in the head, an outside religion, when the heart is not cleansed. God looks at the heart; “all things are naked and opened unto the eyes of Him with whom we have to do.” Will He be satisfied with anything but truth in the inward parts? Every truly converted soul will carry the unmistakable marks that the carnal mind is subdued. 1T 162.4"
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God."
Both passages discuss the transformation of the mind and the rejection of worldly conformity. EGW's statement about subduing the carnal mind and reforming the life echoes the idea of being transformed by the renewing of the mind in Romans 12:2.
"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."
Both passages emphasize the idea of Christ living within the believer and the subjugation of self. EGW's description of self being forgotten and Jesus being magnified aligns with the concept of being crucified with Christ and Christ living in the believer as described in Galatians 2:20.
"For to be carnally minded is death; but to be spiritually minded is life and peace."
Both passages contrast the carnal mind with a spiritual focus. EGW's call to subdue the carnal mind directly relates to the warning in Romans 8:6 that being carnally minded leads to death, while being spiritually minded leads to life and peace.
