Essay: Describe two limitations of science and explain why Christians should be aware of them.


  • The scope of science is limited to the study of created matter and energy in the present. Science cannot study God, for He is the Creator and not bound by the laws of creation. Science cannot explain man's soul, human behavior, or the difference between right and wrong.
  • Science relies on assumptions. al long-held assumption may be treated as fact despite evidence against it.
  • Bias exists because human nature often leads one to see and believe that he wants to be true, not necessarily what actually is true. Bias may cause a scientist to incorrectly interpret the results of an experiment to support his hypotheses when the data actually provides no evidence either for or again his hypothesis.
  • Science can only provide approximate descriptions of the the world works.

be sure you know the quantity and correct metric unit

capacity = liter


mass = kilogram


length = meter


time = second
