"When a man professes to be sanctified, and yet in words and works may be represented by the impure fountain sending forth its bitter waters, we may safely say, That man is deceived. He needs to learn the very alphabet of what constitutes the life of a Christian. Some who profess to be servants of Christ have so long cherished the demon of unkindness that they seem to love the unhallowed element and to take pleasure in speaking words that displease and irritate. These men must be converted before Christ will acknowledge them as His children. SL 16.1"
"Doth a fountain send forth at the same place sweet water and bitter?"
EGW uses the imagery of a fountain producing bitter water to illustrate the inconsistency of a sanctified person exhibiting unkindness, mirroring the sentiment in James 3:11.
"Meekness is the inward adorning, which God estimates as of great price. The apostle speaks of this as more excellent and valuable than gold or pearls or costly array. While the outward adorning beautifies only the mortal body, the ornament of meekness adorns the soul and connects finite man with the infinite God. This is the ornament of God's own choice. He who garnished the heavens with the orbs of light has by the same Spirit promised that “he will beautify the meek with salvation” ( Psalm 149:4 ). Angels of heaven will register as best adorned those who put on the Lord Jesus Christ and walk with Him in meekness and lowliness of mind. SL 16.2"
"For the Lord taketh pleasure in his people: he will beautify the meek with salvation."
EGW directly quotes Psalm 149:4, connecting it to the idea of God beautifying the meek.
"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."
Both passages emphasize the value of inner beauty, specifically meekness, over outward adornment. EGW directly references 1 Peter 3:4 in the broader context.
"There are high attainments for the Christian. He may ever be rising to higher attainments. John had an elevated idea of the privilege of a Christian. He says, “Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God” ( 1 John 3:1 ). It is not possible for humanity to rise to a higher dignity than is here implied. To man is granted the privilege of becoming an heir of God and a joint heir with Christ. To those who have been thus exalted, are unfolded the unsearchable riches of Christ, which are of a thousandfold more value than the wealth of the world. Thus, through the merits of Jesus Christ, finite man is elevated to fellowship with God and with His dear Son. SL 16.3"
"Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not."
EGW directly quotes 1 John 3:1 and expands on its meaning in the context of Christian privilege and fellowship with God.
"And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together."
While EGW quotes 1 John 3:1, the concept of being heirs of God and joint-heirs with Christ is strongly present in both passages, making it a thematic parallel. Romans 8:17 is a strong parallel to the concept of being joint heirs.
