"Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God."
The EGW passage speaks of acting 'in behalf of the church,' which aligns with the idea of being an ambassador for Christ, pleading for reconciliation. The connection is thematic, focusing on representation and advocacy.
"From time to time for the past twenty years I have been shown that the Lord had qualified my husband for the work of faithfully dealing with the erring, and had laid the burden upon him, and that if he should fail to do his duty in this respect he would incur the displeasure of the Lord. I have never regarded his judgment infallible, nor his words inspired; but I have ever believed him better qualified for this work than any other one of our preachers, because of his long experience, and because I have seen that he was especially called and adapted to the work; and also because in many cases where persons have risen up against his reproofs, I have been shown that he was right in his judgment of matters and in his manner of reproving. 1T 612.4"
"When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand."
The EGW passage discusses the burden placed on James White to reprove and deal with erring individuals, and the consequences of failing to do so. This aligns with the principle in Ezekiel 3:18, which speaks of the responsibility to warn the wicked and the consequences of neglecting that duty.
"And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues."
The EGW passage discusses how her husband was 'set' or 'qualified' for a specific role in the church. This echoes the idea in 1 Corinthians 12:28 that God sets different people in the church with different gifts and roles. The connection is thematic rather than a direct quote or principle.
