Linear Scene 1.2: Here is what an open door will look like into heaven. Jesus is showing things exclusive to the future. Further, we cannot miss something significant that just happened: Jesus was speaking to John on Earth about the 7 churches, and now that voice is suddenly in heaven. This lets us know that Jesus' movement from earth to heaven can be communicated through the location of His voice [1:10, 4:1].

Important Note: When we see the saints, they are shown receiving crowns, wearing them, holding harps, and wearing white raiment. The 24 elders seem deeply connected to the image of saints: crowns, thrones, and white raiment. All very particular to saints. It would be safe to postulate that these 24 elders are linked to the church but distinct from the full body of saints, even if they are part of it.

At most, from an interpretive standpoint, these are leaders of saints, but cannot be, by the text itself, a "raptured church".

We should not read into the text what is not there or inferred by reference. For example, one might postulate that these are the twelve apostles (Matthew 19:28 and Luke 22:29-30) and the twelve leaders of Israel, making a total of 24 elders. But if John is observing them, how can he be one of them, as he is an apostle – basically, the text does not tell us their identity beyond their number and general characteristics.

Important Note: From a textual-critical standpoint, prophetic literature demands maximal restraint in translation because its symbolic vocabulary functions through repetition. Revelation 4:5 employs a tightly patterned lexical triad — ἀστραπαί / φωναί / βρονταί ("lightnings/voices/thunders"), that appear at key structural moments (4:5; 8:5; 11:19; 16:18).

Important Note: When we hear the word sea, we usually imagine a vast ocean, turbulent waters, chaos, and depth. But that is not what appears here. Instead, the "sea of glass" with its proximity to the heavenly temple seems closer in concept to the earthly temple's Molten Sea described in 2 Chronicles 4:2-6. But, passages like Exodus 24:10, "And they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness.", may push some readers toward understanding the sea of glass as a kind of pavement or platform. Yet Exodus never speaks of a sea at all; it speaks of a paved work. That makes it difficult to identify Revelation's imagery by symbols alone at this stage. It is not until Revelation 15 that we are given clearer detail about how the sea of glass actually functions, allowing the picture to come into sharper focus. And, of course, it remains possible that the sea of glass, or "glassy sea", is not meant to be fully resolved. Some aspects may intentionally remain mysterious.
