"Those who are true to God will be menaced, denounced, proscribed. They will be “betrayed both by parents, and brethren, and kinsfolks, and friends,” even unto death. Luke 21:16 . Their only hope is in the mercy of God; their only defense will be prayer. As Joshua pleaded before the Angel, so the remnant church, with brokenness of heart and unfaltering faith, will plead for pardon and deliverance through Jesus, their Advocate. They are fully conscious of the sinfulness of their lives, they see their weakness and unworthiness; and they are ready to despair. PK 588.1"
"And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death."
Ellen White directly references Luke 21:16 in this passage.
"And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death."
EGW quotes Luke 21:16, which is very similar to Matthew 10:21, and uses it to describe the persecution faced by those true to God.
"The tempter stands by to accuse them, as he stood by to resist Joshua. He points to their filthy garments, their defective characters. He presents their weakness and folly, their sins of ingratitude, their unlikeness to Christ, which has dishonored their Redeemer. He endeavors to affright them with the thought that their case is hopeless, that the stain of their defilement will never be washed away. He hopes so to destroy their faith that they will yield to his temptations, and turn from their allegiance to God. PK 588.2"
"Now Joshua was clothed with filthy garments, and stood before the angel."
EGW directly references and expands upon the scene in Zechariah 3:3, drawing a parallel between Joshua's situation and the experience of believers facing accusation.
"And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night."
Both passages deal with the accuser (Satan) and his attempts to undermine God's people. While EGW's passage is more specific to individual believers, Revelation 12:10 speaks of a broader, cosmic accusation. The thematic link is strong.
Satan has an accurate knowledge of the sins that he has tempted God's people to commit, and he urges his accusations against them, declaring, that by their sins they have forfeited divine protection, and claiming that he has the right to destroy them. He pronounces them just as deserving as himself of exclusion from the favor of God. “Are these,” he says, “the people who are to take my place in heaven, and the place of the angels who united with me? They profess to obey the law of God; but have they kept its precepts? Have they not been lovers of self more than lovers of God? Have they not placed their own interests above His service? Have they not loved the things of the world? Look at the sins that have marked their lives. Behold their selfishness, their malice, their hatred of one another. Will God banish me and my angels from His presence, and yet reward those who have been guilty of the same sins? Thou canst not do this, O Lord, in justice. Justice demands that sentence be pronoun…
"Then Satan answered the Lord, and said, Doth Job fear God for nought? Hast not thou made an hedge about him, and about his house, and about all that he hath on every side? thou hast blessed the work of his hands, and his substance is increased in the land. But put forth thine hand now, and touch all that he hath, and he will curse thee to thy face."
Both passages depict Satan challenging God and accusing God's people. In Job, Satan questions Job's motives and suggests that Job only fears God because of God's blessings. The EGW passage describes Satan accusing God's people of forfeiting divine protection due to their sins. The parallel lies in the shared theme of Satan challenging God's judgment and accusing God's people.
