"Jesus did not come to the earth as the waiting, joyful company expected, to cleanse the sanctuary by purifying the earth by fire. I saw that they were correct in their reckoning of the prophetic periods; prophetic time closed in 1844, and Jesus entered the most holy place to cleanse the sanctuary at the ending of the days. Their mistake consisted in not understanding what the sanctuary was and the nature of its cleansing. As I looked again at the waiting, disappointed company, they appeared sad. They carefully examined the evidences of their faith and followed down through the reckoning of the prophetic periods, but could discover no mistake. The time had been fulfilled, but where was their Saviour? They had lost Him. EW 243.2"
"It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these."
The EGW passage directly addresses the cleansing of the sanctuary and the nature of its purification, which aligns with the principle discussed in Hebrews 9:23 regarding the purification of heavenly things. The passage clarifies the Millerites' misunderstanding of this concept.
