CLAIM: God’s justice will fill all the earth at Jesus’ Second Coming in the context of a worldwide worship movement (v. 10-12). This passage was partially fulfilled at Jesus’ first coming (Mt. 12:18-20).
As I understand it, this was fulfilled completely in Jesus’ first coming. God may speak a global worship movement out of v10-12, but He has been doing the “new song” for much longer than that. Failure to appreciate that is to dishonor our father’s before us. There may be much more to be said about this chapter, but for now, it is viewed as fulfilled until there are sufficient reasons to say otherwise.
