Friends, why are you doing this? We too are only human, like you. We are bringing you good news, telling you to turn from these worthless things to the living God, who made the heavens and the earth and the sea and everything in them. In the past, he let all nations go their own way. Yet he has not left himself without testimony: He has shown kindness by giving you rain from heaven and crops in their seasons; he provides you with plenty of food and fills your hearts with joy. Acts 14:15-17
Here is the pattern for preaching to a non-religious people. If you want to know how to reach your neighbors who are not interested in the gospel, and who know nothing of Scripture, who have not been to church and are not interested in it, here is the way. The approach is through nature. When Paul went to the Jews, he started with the Scriptures, the truth of God that they already knew. When he went to the Gentiles, he started with nature, the truth of God which they already knew. He points out three things that ought to have been very plain to them if they had been thinking about their contact with nature.
First, he shows that behind creation there is one living God. He appeals to the fact that, if they had really observed nature, they would realize that it is not controlled by a conglomerate of separate powers, all trying to compete with one another, as envisioned in the pagan pantheon. Paul is saying,
You haven’t really seen nature. You haven’t noticed that nature is as one; it all ties together, blending and harmonizing beautifully. It all exists and functions together because it has been made by one God, who is a living God. It is sustained and held together. It doesn’t decay and fall apart but it is constantly being renewed. So there is one living God. Paul declares to them that nature has borne witness to God.
The second point he makes is that the One Living God permits men free choice, and therefore allows evil. One of the problems about God faced by anyone in the world today is,
Why is there evil present among men? This is a constant argument of humanists, and others. They say,
If your God is such a loving God, who loves man, why does he permit suffering? Why does he allow evil, and injustice, and war? These pagans argued the same way. Paul is answering by saying,
What you must know is that God, in generations past, allowed all the nations to walk in their own way. In other words, he gave them free will. To permit free will, he must allow evil.
