And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail. (Revelation 11:19)
19 (see EGW comment on Exodus 31:18; Isaiah 6:1-7; 58:12-14). Tables of Stone a Convincing Testimony
When God’s temple in heaven is opened, what a triumphant time that will be for all who have been faithful and true! In the temple will be seen the ark of the testament in which were placed the two tables of stone, on which are written God’s law. These tables of stone will be brought forth from their hiding place, and on them will be seen the Ten Commandments engraved by the finger of God. These tables of stone now lying in the ark of the testament will be a convincing testimony to the truth and binding claims of God’s law (Letter 47, 1902).
19 Ark in Heaven Contains Commandments
Sacrilegious minds and hearts have thought they were mighty enough to change the times and laws of Jehovah; but, safe in the archives of heaven, in the ark of God, are the original commandments, written upon the two tables of stone. No potentate of earth has power to draw forth those tables from their sacred hiding place beneath the mercy seat (The Signs of the Times, February 28, 1878).
