What does the Bible say about natural theology?

In Romans 1:20-21, it is stated that the invisible things of God are clearly seen and understood through the creation of the world. This underscores that the natural world can reveal God's eternal power and deity, thus rendering humanity without excuse for not glorifying Him. While natural theology has its merits, it reveals only so much about God and cannot replace the necessity of divine revelation found in Scripture. It may lead individuals to acknowledge God's existence, but it cannot communicate the full depth of humanity's sinfulness or the need for a Savior.
