There are several ways by which we can think about the Day of Judgement. We can consider it from what people will be doing when it happens. Jesus tells us that it will be like what happened on the day when the Flood predicted by Noah came. Or we can look at from how the inhabitants of heaven will react when the day arrives. This second viewpoint is what John now details in describing the blowing of the seventh trumpet.
First, we are told that that the kingdom belongs to God the Father and to Jesus – Jesus is described as the Father’s Christ or anointed one. Paul tells us in 1 Corinthians 15 that, after Jesus has overpowered all his enemies and delivered the kingdom to the Father, he will continue to function as the Mediator for ever.
Second, we are told the contents of the trumpet blast, which is that the Father through Jesus will have captured or conquered the world and his eternal reign is about to commence. This is a reminder that the activity of Jesus as the Christ in heaven, which began at his ascension, has two phases. One is between his ascension and his return and the other is from the return into the unending future.
Third, the divine person who is praised here by the heavenly authorities (the twenty-four elders – angels with places of significance on thrones) is the Father, although they do not address him as such, perhaps because they do not have the same level of relationship with him that believers have. Or maybe they use the divine names that stress his authority over those who have rebelled against him. He is the sovereign, almighty, eternal God.
Fourth, the attitude of the heavenly authorities towards this moment in the divine plan is stated. They are grateful that the time for the judgement has arrived. Two reasons are given for their response. One is that those who destroyed the earth by their sinful practices will be judged and the other is that God’s people (prophets, saints and those who fear his name) will be rewarded for their service.
