Then, the researcher will take a sample of people within each specific group using another sampling method like simple random sampling for instance.

<span>A Christian worldview has the stamp of reason and reality and can stand the test both of history and experience.  Every chapter in this book is predicated on a Christian view of things, a view of the world which cannot be infringed upon, or accepted or rejected piecemeal, but stands or falls in its integrity.  Such a wholistic approach offers a stability of thought, a unity of comprehensive insight which bears not only on the religious sphere, but on the whole of thought.  A Christian worldview is not built on two types of truth (religious and philosophical or scientific), but on a universal principle and all-embracing system that shapes religion, natural and social sciences, law, history, healthcare, the arts, the humanities, and all disciplines of study with application for all of life. </span>
