There has been a universal proclamation of the gospel through nature. Everywhere people know something about God. He is revealed in nature. There is a universal proclamation in nature itself, which if observed, if noticed and followed, will result in more light given. Israel rejected the message concerning Christ.
Many today also reject it as well.
But God is patient. He continues to show mercy. Here is the truth of the matter. Even though people reject Him, God is patient with them. He has held out His hands to Israel for four thousand years.
