What does Revelation 15:8 mean?
As the fires of judgment burn, the sanctuary in heaven fills with smoke. The smoke arises from God's glory and power. From this time until the end of the tribulation, when the seven plagues end, no one is allowed to enter the temple in heaven. An event similar to one described in this verse occurred after Moses finished the work of building the tabernacle and furnishing it. Exodus 40:34–35 says, "Then the cloud covered the tent of meeting, and the glory of the LORD filled the tabernacle. And Moses was not able to enter the tent of meeting because the cloud settled on it, and the glory of the LORD filled the tabernacle."Similarly, when Solomon dedicated the temple, "fire came down from heaven and consumed the burnt offering and the sacrifices, and the glory of the LORD filled the temple. And the priests could not enter the house of the LORD, because the glory of the LORD filled the LORD's house" (2 Chronicles 7:1–2). Without God's gracious invitation to draw near to Him, no human being would ever be able to survive the glory of His presence.
