"builders disallowed, the same is made the head of the corner, and a stone of stumbling, and a rock of offense, even to them which stumble at the word, being disobedient: whereunto also they were appointed. But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of Him who hath called you out of darkness into His marvelous light.” 1 Peter 2:7-9 . Then your hand firmly grasped the true banner, and these encouraging words were spoken: “Let us be glad and rejoice, and give honor to Him: for the marriage of the Lamb is come, and His wife hath made herself ready. And to her, was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.” Revelation 19:7, 8 . 8T 154.1"
"Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner, And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed. But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:"
Ellen White directly references 1 Peter 2:7-9 in this passage.
"You and your associates in the sanitarium work need a pilot with you constantly, else you will be shipwrecked. You surely must understand your peril. Satan is making every effort to turn you aside into strange paths. God has strengthened you. Your soul must be sanctified through the truth, that your steadfast adherence to principles may be plain to all. The more fully your helpless soul leans upon God, the more fully you make Him your trust, the more hungry you will become for the bread of life. 8T 154.3"
"Holding faith, and a good conscience; which some having put away concerning faith have made shipwreck:"
Both passages use the metaphor of 'shipwreck' to describe a loss of faith or spiritual grounding. EGW's passage warns of spiritual shipwreck if they don't have a 'pilot' (God) and adhere to principles.
