Vision of purification
The revealer of the vision is either the interpreting angel or, more likely, God himself (cf. 1:20). As has been said, Joshua represents Israel in her priestly character. The scope of this passage demands that interpretation. Then, too, in v.8 Joshua and his colleagues are definitely said to be symbolic of the future. The Angel of the Lord must be deity, for in v.2 he is specifically called “the LORD.” Thus he clearly represents God. “Standing before the … LORD”

God’s sovereign choice of Jerusalem in grace shows the unreasonableness of Satan’s attack (cf. Rom 8:33). The reference to the burning stick snatched from the fire is an additional indication that Israel, not Joshua, is ultimately in view. Israel was retrieved to carry out God’s future purpose for her (cf. Amos 4:11). The “fire” refers to the Babylonian captivity. Metaphorically, Israel was snatched as a burning stick from that fire. However, this event may also look back to the deliverance from Egypt (cf. Deut 4:20; 7:7–8; Jer 11:4) and forward to the rescue from the coming tribulation period (cf. Jer 30:7; Zech 13:8–9; Rev 12:13–17).
The festive garments (the Hebrew word is used only here and in Isa 3:22 speak of purity, joy, and glory; but their chief significance is that they symbolize the restoration of Israel to her original calling (Exod 19:16; Isa 61:6). There is a contrast here: Joshua in filthy garments—Israel as a priest but defiled and unclean; Joshua in festive garments—Israel’s future glory in reconsecration to the priestly office. “I have taken away” emphasizes the agent of the forgiveness. It is God who causes sin to be removed, ultimately on the basis of the messianic Servant’s substitutionary death. But note that here it was actually the Angel of the Lord who forgave sin, thus identifying him as deity (cf. Mark 2:7, 10).
It seems best and more consistent with the context however, to take it as another figure of the Messiah (cf. Bullinger, pp. 896–97). To the Jews at his first advent, the Messiah (Christ) was the stumbling stone and rock of offense (Isa 8:13–15; cf. Ps 118:22–23; Matt 21:42; 1 Peter 2:7–8). But to those who trusted in him, he was a never-failing refuge (Isa 28:16; 1 Peter 2:6). Moreover, he is to be the smiting stone to the nations (Dan 2:35, 45). At present he is the foundation and chief cornerstone of the church (Eph 2:19–22). And to restored Israel in the Messianic Era, he will be the dependable rock of the trusting heart.
The exhortations in Paul’s various letters in the New Testament are always based securely on the theology of grace through Christ. For instance, the call to walk in holiness in Ephesians 4–6 (“live a life worthy of the calling you have received,” 4:1) is based on all the blessings we have received “in Christ” in Ephesians 1–3 (e.g., 1:3). So also the exhortation to “offer your bodies as living sacrifices, holy and pleasing to God,” which introduces a series of commands in Romans 12–15, is based securely on “God’s mercy” (12:1), which is explicated in detail in Romans 1–11.
