"Saddest of all words that ever fell on mortal ear are those words of doom, “I know you not.” The fellowship of the Spirit, which you have slighted, could alone make you one with the joyous throng at the marriage feast. In that scene you cannot participate. Its light would fall on blinded eyes, its melody upon deaf ears. Its love and joy could awake no chord of gladness in the world-benumbed heart. You are shut out from heaven by your own unfitness for its companionship. COL 413.1"
"And then will I profess unto them, I never knew you: depart from me, ye that work iniquity."
EGW directly quotes and expands upon the idea of being unknown by Christ, drawing a clear parallel to Matthew 7:23. The phrase "I know you not" is central to both passages.
"We cannot be ready to meet the Lord by waking when the cry is heard, “Behold, the Bridegroom!” and then gathering up our empty lamps to have them replenished. We cannot keep Christ apart from our lives here, and yet be fitted for His companionship in heaven. COL 413.2"
"And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut."
The EGW passage directly references and interprets the parable of the ten virgins, specifically the moment the bridegroom arrives. The phrase "Behold, the Bridegroom!" is a direct quote, and the context is clearly the same.
