These words may be related back to what Christ had said earlier. In verses 11 and 12 of this chapter, you read: ‘And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables: 12 That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them.
This applies to life in this world. There are some things which are concealed from us in life. The world won’t speak about them, the world resents them, it contradicts them. Here is an obvious one: that we are sinful, that we are depraved. The world doesn’t tell you that, in fact the world works quite hard at disproving this. ‘No, nobody is an absolute sinner. Nobody is as bad as you make out.’ It wants self-confidence and self-approval. It wants to think well of itself. However, the light of the gospel uncovers things that the world covers up and it says, ‘No, we are sinners. We are depraved. We cannot please God. We cannot have his blessing.’ Now, if you are used to hearing this message as a Bible believer, as a worshipper, you say, ‘Well, that’s not so surprising.’ Actually, it is! You won’t hear a message like that in the world! You won’t hear anywhere that mankind is depraved and that we need salvation and we need total change of life. The gospel says that we are alienated from God, we are cut off from him. The world doesn’t agree with that; it tries to bury God’s truth. The world is full of phoney religions, counterfeit religions, telling us that it is comparatively easy for us to please God, if we just follow their way: religions of self-righteousness and of works. But the gospel isn’t like that. It makes manifest and shows things that the world keeps secret. It speaks of God’s absolute, perfect holiness. He cannot abide sin and he must judge us all. It speaks of God’s amazing mercy in sending a Saviour to suffer and die in our place, if we trust in him and believe in him. It speaks about the emptiness and the vanity of the world, and about hell and punishment, and the world recoils from this. ‘There is nothing hid, which shall not be manifested.’ When? In the last day, when the books are opened and the deeds of every man and woman are revealed. So it has a long-term sense as well. Therefore, ‘if any man have ears to hear, let him hear.’ That is a very solemn expression which signals that something very profound and important is being said. So now is the time will come for plain speech and open preaching.
