"you will perfect it until the day of Jesus Christ: even as it is right for me to be thus minded on behalf of you all, because I have you in my heart.” “Therefore, my brethren dearly beloved and longed for, my joy and crown, so stand fast in the Lord, my dearly beloved.” “Now we live, if ye stand fast in the Lord.” Verse 16 , A.R.V.; Philippians 1:3-5 ; 1:6, 7 , A.R.V.; 4:1 ; 1 Thessalonians 3:8 . MH 167.1"
"Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:"
The EGW passage directly quotes Philippians 1:6, making it an explicit allusion.
"I thank my God upon every remembrance of you, Always in every prayer of mine for you all making request with joy, For your fellowship in the gospel from the first day until now;"
Ellen White directly references Philippians 1:3-5 in this passage.
"For now we live, if ye stand fast in the Lord."
Ellen White directly references 1 Thessalonians 3:8 in this passage.
"When one at fault becomes conscious of his error, be careful not to destroy his self-respect. Do not discourage him by indifference or distrust. Do not say, “Before giving him my confidence, I will wait to see whether he will hold out.” Often this very distrust causes the tempted one to stumble. MH 167.3"
"Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted."
Both passages emphasize restoration and avoiding actions that could cause further stumbling. EGW expands on the practical application of Galatians 6:1, specifically addressing the need to avoid distrust and discouragement.
