Here's Bavinck on the importance of common grace in the Reformed tradition:

"However much [the church] might be on its guard against paganism, it never despised or condemned natural life as in itself sinful. Marriage and family life, secular calling and military estate, the

swearing of the oath and the waging of war, government and state, science and art and philosophy, - all these were recognized from the beginning as divine institutions and as divine gifts. Hence theology early began to form relations with philosophy; the art of painting, as

practiced in the catacombs, attached itself to the symbols and figures of antiquity; architecture shaped the churches after pagan models; music availed itself of the tunes which Graeco-Roman art had produced. On every hand a strong effort is perceptible to bring the new religion

into touch with all existing elements of culture.

It was possible for the first Christians to do this because of their firm conviction that God is the Creator of heaven and earth, who in times past has never left Himself without witness to the heathen... No doubt among the

heathen this wisdom has in many respects become corrupted and falsified; they retain only fragments of truth, not the one, entire, full truth. But even such fragments are profitable and good... The good philosophical toughs and ethical precepts found scattered through the pagan

world receive in Christ their unity and center. They stand for the desire which in Christ finds its satisfaction; they represent the question to which Christ gives the answer; they are the idea of which Christ furnishes the reality. The pagan world, especially in its philosophy,

is a pedagogy unto Christ; Aristotle, like John the Baptist, is the forerunner of Christ. It behooves the Christians to enrich their temple with the vessels of the Egyptians and to adorn the crown of Christ, their king, with the pearls brought up from the sea of paganism.
...

[arts and sciences] should be considered gifts of the Holy Spirit. It is true the Holy Spirit as a spirit of sanctification dwells in believers only, but as a spirit of life, of wisdom and of power He works also in those who do not believe. No Christian, therefore, should despise

these gifts; on the contrary, he should honor art and science, music and philosophy and various other products of the human mind as praestantissima Spiritus dona (most superior gifts of the Spirit), and make the most of them for his own personal use.

...much more strongly

than Luther, Calvin emphasizes the idea that life itself in its whole length and breadth and depth must be a service of God. Life acquires for him a religious character, is subsumed under and becomes a part of the Kingdom of God.
...
[Calvin] found the will of God revealed not

merely in Scripture, but also in the world, and he traced the connection and sought to restore the harmony between them... Nothing is unclean in itself; every part of the world and every calling in life is a revelation of the divine perfections...
