Common Grace is a theological concept, primarily in Reformed and Calvinistic circles, referring to God’s common patience or forbearance with sinful man ... the non-saving sustaining grace of God that is common to all humankind. It is “common” because its benefits are experienced by, or intended for, the whole human race without distinction between one person and another. It is "grace" because it is undeserved and sovereignly bestowed by God. In this sense, it is distinguished from the Calvinistic understanding of "special" or "saving" grace, which extends only to those whom God has chosen to redeem. An example of the concept can be found in the idea that God allows the sun to shine upon both the righteous and the unrighteous and sends rain on both the just and unjust.
