"Important are the lessons to be learned from the experience of the Hebrew youth on the plain of Dura. In this our day, many of God's servants, though innocent of wrongdoing, will be given over to suffer humiliation and abuse at the hands of those who, inspired by Satan, are filled with envy and religious bigotry. Especially will the wrath of man be aroused against those who hallow the Sabbath of the fourth commandment; and at last a universal decree will denounce these as deserving of death. PK 512.1"
"And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed."
Both passages describe a scenario where people are threatened with death for refusing to comply with a religious decree. EGW draws a parallel between the experience of the Hebrew youth and a future persecution, echoing the themes of Revelation 13:15.
"men will sink into insignificance beside the word of the eternal God. Truth will be obeyed though the result be imprisonment or exile or death. PK 512.2"
"And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell."
Both passages address the idea of prioritizing obedience to God's word even in the face of physical threats, including death. While not a direct quote, the sentiment aligns with Matthew 10:28.
