Albert M. Wolters introduces two helpful concepts in worldview thinking in his book Creation Regained. These two terms are "structure" and "direction."

"Philosophy can be described as that comprehensive (totality-oriented) scientific discipline which focuses on the structure of things--that is, on the unity and diversity of creational givens. Theology (i.e., Christian systematic theology), on the other hand, can be said to be that comprehensive (totality-oriented) scientific discipline which focuses on the direction of things--that is on the evil that infects the world and the cure that can save it. Christian philosophy looks at creation in the light of the basic categories of creation. A worldview, by contrast, is equally concerned with both structural and directional questions."
