"Then Jesus’ silver trumpet sounded, as He descended on the cloud, wrapped in flames of fire. He gazed on the graves of the sleeping saints, then raised His eyes and hands to heaven, and cried, “Awake! awake! awake! ye that sleep in the dust, and arise.” Then there was a mighty earthquake. The graves opened, and the dead came up clothed with immortality. The 144,000 shouted, “Alleluia!” as they recognized their friends who had been torn from them by death, and in the same moment we were changed and caught up together with them to meet the Lord in the air. EW 16.1"
"For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:"
The EGW passage directly alludes to 1 Thessalonians 4:16, describing Jesus' descent with a shout and the resurrection of the dead. The trumpet sound and the awakening of the sleeping saints are key elements found in both texts.
"We all entered the cloud together, and were seven days ascending to the sea of glass, when Jesus brought the crowns, and with His own right hand placed them on our heads. He gave us harps of gold and palms of victory. Here on the sea of glass the 144,000 stood in a perfect square. Some of them had very bright crowns, others not so bright. Some crowns appeared heavy with stars, while others had but few. All were perfectly satisfied with their crowns. And they were all clothed with a glorious white mantle from their shoulders to their feet. Angels were all about us as we marched over the sea of glass to the gate of the city. Jesus raised His mighty, glorious arm, laid hold of the pearly gate, swung it back on its glittering hinges, and said to us, “You have washed your robes in My blood, stood stiffly for My truth, enter in.” We all marched in and felt that we had a perfect right in the city. EW 16.2"
"After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;"
The EGW passage shares strong thematic parallels with Revelation 7:9, particularly the imagery of a multitude clothed in white robes and the idea of victory. While the details differ (crowns, sea of glass), the core theme of the redeemed entering God's presence is consistent.
