The divine power, which created and governs all existing things, can be understood in four different ways:  First, that all these things were not made but are eternal in the dispensation of the Word of God, which, as the Apostle testifies, predestined us for his kingdom before the times of the world.

Second, that the elements of the world were made all at the same time in unformed matter, when he who lives eternally created everything at once.

Third, that the same matter is formed into a heavenly and an earthly creation, partly from existing causes, and partly from causes not yet existing, but each thing coming into existence by the distinct workings of the first six days.

Fourth, that the temporal constitution of the whole world is brought about in the natural course of things by the seeds and primordial causes of this same creation, wherein the Father and the Son work right up to the present, and God even feeds the ravens and clothes the lilies.

Bede, On The Nature of Things c. AD 600’s, England

The fourth way of understanding the divine power is presently the prevailing way among those Christians who work within the current hot big bang theory of cosmology, and the evolutionary model of life.   The third way of understanding is the approach by the literalist six day creation week approach.   The first and second are most suited for use in a steady state approach.
