10:1 Whereas a few commentators have identified this strong angel as Jesus Christ,341the evidence for his being simply another (Gr. allon, another of the same kind) strong angel seems more convincing (cf. vv. 5-6). Other commentators have identified him as Gabriel or Michael (cf. Dan. 8:16; 12:7),342but this is only guessing. He is probably not the same strong angel John saw before (5:2) since there are many strong angels (cf. 18:21). John saw him descending from heaven as a messenger of God (cf. 20:1) and robed in a cloud signifying his celestial origin and connection with judgment (cf. 1:7; 14:14, 15, 16; Matt. 24:30; 26:24; Mark 13:26; 14:62; Luke 21:27). His crown was a rainbow, the symbol of God's faithfulness and mercy (cf. 4:3). His countenance was radiant reflecting the glory and majesty of God. His feet (and legs) were fiery reminiscent of the pillar of fire in the wilderness, a manifestation of God's holiness, mercy, and judgment.
"This scene marks a significant change in John's literary method. Here his personality re-emerges as it did briefly between the sixth and seventh seals (7:13-14), but now for the first and last time in this drama, he leaves the observer's corner and occupies the very center of the stage (e.g., 10:9-11). This new role also involves a change in location from heaven to earth, as the angel descends from heaven (10:1) and stands upon the earth where John hears a voice from heaven (10:4, 8) and goes to him (10:8) . . . The new style is one element among others that heightens the anticipation and accentuates the solemnity of the apocalyptic events to follow."343
10:2 The little scroll in his hand must be different from the scroll Jesus Christ unrolled (5:1; 6:1). John used a different and rare Greek word to describe it (biblaridion, not biblion). The tense of the Greek verb translated "was open"(perfect passive) indicates that someone had opened it and it was then open in his hand. It probably represents a new revelation from God (cf. Ezek. 2:9-3:3; Jer. 15:15-17). The angel stood astride the earth and the sea symbolizing his authority over the whole world (vv. 5, 8; 7:2; cf. Exod. 20:4, 11; Deut. 11:24; Ps. 68:22; 69:34). The implication is that his message involves the whole world. Other less likely views, I think, are that his stance symbolizes the universality of the message,344or that he was defying the sea's instability.345
10:3 His majestic, loud cry produced seven peals of thunder. Comparison with a lion suggests that his powerful cry concerns vengeance. This proves true if what he cried out appears in verse 6. Thunder warns of coming storms, more judgments. These thunders spoke.
10:4 An authoritative voice, probably belonging to God or Christ (cf. 1:11, 19; Dan. 12:4, 9), did not permit John to record the judgments these seven thunders revealed (cf. 2 Cor. 12:1-4). This indicates that God has not revealed in Scripture all the judgments that will take place on the earth during the Great Tribulation.346
Apparently John used the intervals between events in his visions to write down what he had seen and heard or at least to make notes.
