"I have more understanding than all my teachers, for Your testimonies are my meditation. I understand more than the aged, for I keep Your precepts."
With these words, the anonymous author of Psalm 119 reveals what is at the heart of the continuous controversy over the question of ultimate origins.
As are all men, unbelieving scientists (and their representatives in education and the popular media) are fallen; they are sinners. Thus, their moral natures are corrupted. However, they continue to be men, so they have the ability to reason. It isn't their ability to reason which is misaligned, but rather their worldview, which is built on erroneous premises.
As a rational human being, a scientist, a bureaucrat, or an educator, has the ability to study and describe the relationships among living things, such as between a plant and its pollinator, or between a carnivore and its prey. Where they fail is their inability to acknowledge the relationship of each creature or species to its Creator. Only a believer can recognize that.
The Apostle Paul describes this contrast in I Corinthians 2:14, "The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them, because they are spiritually discerned."
This is the problem with court decisions which have banned the discussion of biblical creation, on the basis of "religious neutrality." Secularism isn't "spiritually-neutral." It is a contrary spiritual worldview, a view which has been given legal preference over orthodox Christianity.
