The power of prayer

Sermon: Sunday, 24th August, 2025
Speaker: John Johnstone
Scripture: Revelations 8:1-5

It’s been several weeks since we were last in Revelation, so let’s recap. In chapter 5, we saw a scroll with writing on both sides in the hand of God the Father. This scroll symbolises God’s plans for human history. At first, no one could be found worthy to open the scroll, and bring God’s plans to fulfilment. However, there is a lion-like Saviour who is going to put things right! This lion is also a Lamb who has been slain.

In chapter 6, we were introduced to the four riders of the apocalypse. Through these coloured horses, and the opening of the first four seals, God is telling us what must take place between the first coming and second coming of Jesus, which includes right now. God wants us to be prepared for the great suffering on the earth from the time of Jesus’ ascension, until the day he returns, at the end of the world. God says to expect a world of military conquest (the white horse), war (the red horse), famine (the black horse) and death (the pale horse). And this is exactly our experience of life. God’s warning is exactly right. The fifth seal transported us from the earth up into Heaven, where the martyrs ask God how long the suffering of Christians on earth must last for; God tells them it will be until he has finished gathering in all the saints. Then, most soberingly, we saw that the opening of the sixth seal marks the Day of Judgement. A great shaking and destroying of all evil will take place. The sun turns black and the stars fall from the sky. The universe is being dismantled. The end has come. Those who have rejected God in this life will have nowhere to hide from God’s justice on that day. They will have missed their opportunity to receive God’s mercy. They must now face the consequences of their own failures.

If the opening of the sixth seal seemed too climatic, with the whole universe being dismantled, what is going to happen when Jesus opens the seventh seal? Will the earth melt with fire? After the action-packed descriptions of seals 1-6, the last seal might seem to arrive with a sense of anti-climax: ‘When he opened the seventh seal, there was silence in heaven for about half an hour.’   (Revelation 5:1) There is not much silence in the book of Revelation; usually we hear loud cries of praise on the sound of war or a loud voice speaking, but not silence. What are we to make of it? The silence is deafening. It is an intense and overwhelming silence, like the calm before a storm.

1. Evil will be punished

As we have seen again and again, the best key to unlock the imagery in Revelation is the Old Testament. What does silence signify there? There are many Old Testament passages which link silence to the righteous judgment of God. For example, in Isaiah 23 v2, when Tyre is being judged by the Lord, we read: ‘Be silent, you people of the island and you merchants of Sidon…’   (Isaiah 23:2) And in the book of Zephaniah, God gives a prophecy about judging the whole earth on the day of the Lord: ‘Be silent before the Sovereign Lord, for the day of the Lord is near.’   (Zephaniah 1:7) This is a holy and reverent silence before divine judgment takes place.

The silence, then, signals to us here this morning that there will be a day when we are all brought to account for how we have lived. We cannot live any way we please and ignore God with impunity. Why does this silence last for half an hour? I am not sure. Perhaps it signals how suddenly this judgment will come upon us. We need to be ready for it, by becoming followers of Jesus.

Many Christians today struggle with the truth of God’s judgment. Some are emotionally troubled by it and others might feel even stronger and be morally outraged by it. The fear is that hell will be an unfair punishment and that it does not square with a loving God. These are genuine concerns people wrestle with. I’ve got several questions about hell myself which I don’t know the answer to. I leave these things with the most loving, just and fair being in the universe – God himself.

Recently, I read a helpful article by Rebecca McLaughlin about the link between love and anger:

‘The idea of the wrath of God seems alien to us a psychologically damaging relic from a bygone era. But just as we cannot absolve people of moral accountability without also erasing their ability to love, so God’s love and God’s judgment cannot be pulled apart. Think of the anger you feel when you see school children shot, women raped, or people beaten because of the colour of their skin. Think of your anger at the slave trade, the Holocaust, and global sex trafficking. When you analyse that anger, its root is love. No one who regards those of other races as subhuman cares about racial exploitation. No one who believes that women or children are property cares about sexual abuse. And the more we love, the more easily our anger is kindled. We rush to defend our children from the least attack because we love them: anyone who harms them inspires our fury.

Imagine that this kind of love-motivated anger is so deeply entrenched in the heart of God that your own commitment to justice is like a drop in the ocean, like the justice of a child dressing up in a police outfit compared with a high-court judge.’

In 2014, it came to light that Jimmy Savile was not the man we might have thought he was. Yes, he raised 40 million for charity. But the truth is that he was a sexual predator who never received punishment for his decades of criminal activity. Did he get away with it? No. He will be brought to account by God. We all will.

Earlier in the month, the Steadfast Global prayer notes told us about Nigeria: ‘Violent attacks against Christian communities are continuing across Plateau state with a further 17 Christians killed by suspected Fulani Muslims since 15 July’. From a human point of view, these attackers got away with it. But have they? Do you want to live in a world where evil actions do not matter? Yes, for many hell is a tough truth to wrestle with. But a universe without justice is also an awful thought. And we can be sure that God will never over-react when meting out punishments. It will be done with absolute fairness. Jesus says, ‘But I tell you that it will be more bearable for Sodom on the day of judgment than for you.’   (Matthew 11 v 24:) In other words, there will be different levels of punishment in hell.

What will we say to the Lord when we stand before him in judgment? What will Savile say? What will the Fulani herdsman say? Will we be complaining to God about how unfair the punishment is going to be? ‘Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God.’   (Romans 1:19) Every mouth will be silenced because God will be judging us and not the other way round. Evil will not remain unpunished forever.

2. The power of prayer

Is there really any point in praying to God? What difference does it make? If we look closely at these few verses it ought to be a massive encouragement to us to pray more. Prayer makes all the difference. Who exactly is praying here? Verse 3 says it is the prayers of ‘all of God’s people’. It is the prayers of all the saints. That includes the prayers of us here this morning, if we are Jesus’ disciples. And what happens to our prayers when they are uttered? They do not bounce of the ceiling and get lost. They do not enter a black hole. Rather, they reach the front of the throne of God. In other words, God hears them. The King of the Universe listens to us personally.

If we all wrote letters to Keir Starmer expressing our various concerns and needs, I very much doubt we would get a personal reply. The letters will go through a screening process at his office with many being ignored. Probably, one of his secretaries will send us a generic reply to some people. How many letters does the prime minister get each day? How many does he read and respond to and take action on personally? A very small number. God is the opposite.

Notice that our prayers are mixed with incense. What does this tell us? That our prayers are like a sweet smelling aroma to our heavenly Father. Do you believe that? That’s why we sang from Psalm 141: ‘May my prayer be set before you like incense; may the lifting up of my hands be like the evening sacrifice’. Even when we do not know what to pray for and we cry out to God, and even when our prayers are mixed with wrong motives and faltering faith, because Jesus is our perfect sacrifice and we are united to him in faith, he makes our prayers acceptable to the Father. When we pray in Jesus’ name, our prayers are covered by Christ’s blood and ascend clean and beautiful and bring joy to our Father. Isn’t that wonderful?

There’s the story of a very young girl picking flowers for her mother. An older woman sees what she has gathered and says ‘let me help you – I’ll take out the weeds and the dirt’. And she does. And the girl gives this beautiful bouquet of flowers to her mother. This is what Jesus does with our prayers. He perfects them for us. He intercedes for us.

Here’s the most exciting part – God not only hears our prayers but he responds by taking action. Our prayers are influential. Far from being a waste of time, they result in the action of God.

Kevin Deyoung: ‘God has ordered the world so that our prayers make a difference. He has sovereignly ordered the world so that he responds to prayer. His sovereign purposes are accomplished through his people praying. The hands that fold in prayer move the hands of him who made the world.’

We see the truth of this as the Lord responds to the prayers of the persecuted church by finally bringing judgment on those who have attacked his church: ‘Then the angel took the censer, filled it with fire from the altar, and hurled it on the earth; and there came peals of thunder, rumblings, flashes of lightning and an earthquake.’   (Revelation 5:5)

Remember what happened when the 5th seal was opened. The martyred saints in Heaven pray: ‘They called out in a loud voice, ‘How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood?’ Then each of them was given a white robe, and they were told to wait a little longer, until the full number of their fellow servants, their brothers and sisters, were killed just as they had been.’ (Revelation 6:10-11) God answers their prayers at the end of time.

When I think back over the last 30 years, I should have been more politically involved. I could have written more letters to MPs to both encourage and challenge. But there’s something much more powerful I could have done more of – and that’s pray. Because our prayers are more powerful than we realise. God uses them for the outworking of his purposes. I believe God pays more attention to our prayers and uses our prayers more than he does with the political structures we have. Political structures are important and we ought to be involved in them, but the power of prayer is more important than politics. May this remind us to pray for our politicians.

If we take this passage seriously, and if we really believe that God uses our prayers to fulfil his eternal decree then we won’t need to have our arm twisted to come to the prayer meeting or to pray more at home. If we trust prayer makes a difference it is likely we shall do it.
