The polytheistic religion of Greeks said that there were many gods. There were as many divine plans and as many purposes as there were gods. Since the gods interacted in a chaotic fashion, people had no guarantee that the world would show any stable order. Greek religion discouraged any hope for a scientific exploration of a rational order.
Modern science arose in the context of Christian monotheism, which displaced the Greek gods and gave confidence to prospective scientists by means of three fundamental principles:
One rational God rules all things (Genesis 1:1; Psalm 33:6), and so we can expect universal order.
God made man in his image (Genesis 1:26-27), and so man is naturally in tune with God’s mind and has hope of grasping the order that God had given.
The world that God made is not divine, and hence is open for human investigation.
In fact, God’s word is the foundation for scientific law. According to Genesis 1, God by speaking specified the regular order for the sun and moon and stars, and the regular pattern for the growth and reproduction of plants (Genesis 1:11, 14-15). What scientists call scientific law is in fact their guess about God’s law, God’s specification, “let it be so.” Scientists in their investigation are in fact investigating the mind of God and thinking his thoughts after himalbeit on their limited, human level.
Early scientists like Copernicus and Isaac Newton understood that they stood before God’s workmanship.
