- The physical universe is an objective reality, which is ontologically distinct from the Creator (Genesis 1:1; Psalm 90:2; John 1:1).
2. The laws of nature exhibit order, pattern, and regularity, since they are established by an orderly God (Psalm 19:1-4; Romans 1:18-21).
3. The laws of nature are uniform throughout the physical universe, since God created and providentially sustains them. Miracles are not violations of natural laws, but supernatural interventions at specific times and for specific reasons.
4. The physical universe is intelligible because God created us to know him, ourselves, and the rest of creation. (Genesis 1-2; Psalm 36:9; Proverbs 8).
5. The world is good, valuable, and worthy of careful study, because it was created for a purpose by a perfectly good God (Genesis 1). Humans, as the unique image bearers of God, were created to discern, discover, and develop the goodness of creation for the glory of God and human betterment through work. The creation mandate (Genesis 1:26-28) includes scientific activity.
6. Because the world is not divine and is therefore not a proper object of worship, it can be an object of rational study and empirical observation.
7. Human beings possess the ability to discover the universe’s intelligibility, since we are made in God’s image and have been placed on earth to develop its intrinsic possibilities. The world and humans were designed for discovery.
8. Because God did not reveal everything about nature, empirical investigation is necessary to discern the patterns God laid down in creation.
9. The intellectual virtues essential to carrying out the scientific enterprise (studiousness, honesty, integrity, humility, and courage) are commanded as part of God’s moral law (Exodus 20:1-17) and are the available through the power of the Holy Spirit (Galatians 5:13-25).
