Through this chapter we shall see predominantly the first aim of the gospel. The primary aim of the preaching of the gospel of redemption – and that is really paramount in this chapter – is of course the great call to repentance.
Now that is reasoning, and that is how we reason in the gospel. To explain this by way of contrast: a few years ago the cry from some misguided people was, ‘Smile, Jesus loves you.’ Their message to sinners was this: ‘God loves you and has a wonderful plan for your life.’ Can you imagine Jeremiah saying that? Can you imagine him going into Jerusalem and saying that? No, he is saying, ’Look, you have got to change your mentality. You have got to get an escape mentality, a fleeing mindset. You are in serious danger; your city is about to be destroyed. There is a place of refuge and hope and safety, but you have got to pursue that.’ That is the tone of the gospel. There is mercy; there is kindness. The preacher does not start with the benefits: ‘God will give you a happy life; God will keep your marriage together; God will take you to heaven. Just believe in Jesus and you will go to heaven.’ No, you start by warning of the wrath to come. You have got to do it in a spirit whereby people will listen, but this is a fallen people, and we have fallen hearts, and are sinners against God, and this is a message of mercy, and conversion, new life, pardon and forgiveness. Before God speaks to us we think we are going to live for ever. It never occurs to us that we have to face God. But without Christ, we have no defence against sin and our appetites which are all for self, and we do not know how to combat the propaganda of the world. That is the picture, which is enshrined in this chapter: ‘Don't call out for Jerusalem to be delivered; it’s too late for that. Be concerned about your safety, and follow the message.’ That is the opening argument to create the right mindset, the right approach for evangelism, for the gospel.
Interestingly, this is repeated in the warnings of Christ in Matthew 24 to the believers, when the desolation referred to in the Book of Daniel comes, and the Roman troops come to sack and destroy Jerusalem. Then they are to flee to the mountains of Judaea. History repeats itself. That is going to be the place of safety. Believers, you are to get out of Jerusalem; it is going to be sacked, and you are to go all the way down to the wilderness of Judaea. Your enemy won't go there; there is nothing to conquer there; there are no cities, no glory; just scattered people living poorly, scratching a living from the desert. So you are safe. The same idea is repeated in the Book of Revelation. What is the place of the church? In the wilderness, in a place that God has prepared for her, a place where he will protect her. Jeremiah’s preaching is that to avoid Nebuchadnezzar and the Chaldean invasion, the people who will listen to him will get out of Jerusalem and they will flee south and light a beacon at Bethhaccerem, a beacon of hope. This is blazing the way to deliverance, and they will take the further road on to Tekoa. When they get there the trumpets will sound to gather them to worship, trumpets of triumph. They have landed in a place where there will be deliverance through the invasion.
