Is God's grace common? Absolutely not! Grace is a soteriological term that is reserved exclusively for the elect of God. Every time God’s grace is mentioned in Scripture, it is always salvific in its character. Exegetically and theologically, grace is the essence of the Gospel, and is God’s unmerited favor towards His elect for whom His Son died. In addition, the Bible principally teaches that God’s grace is discriminative, free, absolute, eternal, efficacious, and immutable. Again, there is nothing common about God’s grace.
If you believe in the common grace notion, show me in Scripture where you see the God's “grace” applied to the reprobate. Respectfully, I am not interested in what you think is the implication of a specific text. If you believe Scripture teaches common grace, show me where God's “grace” is used in either the Hebrew or Greek text to all without exception.
Moderate Calvinists appeal to Matt. 5:45 to argue that God provides common grace to the reprobate because it states that “…He [God] makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust.” Listening to moderate Calvinists twist Matt. 5:45 is similar to how Arminians interpret John 3:16. In my book, High Calvinism, I explained why Matt. 5:43-48 has nothing to do with common grace:
No one should argue that Matt. 5:43-48 does not refer to God’s providence. Providence is not dispensed for the reprobate’s sake, but in accordance with God’s divine prerogatives. Clearly, rain and sunshine are particular aspects of providence. But the rain and sunshine in this aforementioned text is not referring to particular aspects of God’s love, or any overtures of grace, nor does it state that there is in God a benevolent lovingkindness towards the repentance and salvation of even those whom He has not decreed to save. Nowhere in Matt. 5:43-48 does it state that God loves His enemies or the reprobate, nor does it reference God’s motive to pour out blessings to the reprobate. God does not love nor does He provide grace to the wicked. His grace and love are reserved for the elect only. God is against the reprobate. And that is characterized by His immutable hatred for them..
For the record, there is nothing common about grace. Again, every time God's grace is mentioned in Scripture, it is always salvific in its character. Therefore, when men argue that grace is common, they are injecting their own deluded presuppositions into the text, and they are grossly redefining the meaning of a salvific doctrine [God’s Grace]. Study church history to see what kind of men are notable for redefining soteriological terms.
Also, denying the common grace myth is not hyper-Calvinism. What is a hyper-Calvinist? A hyper-Calvinist is one who restricts the preaching of the Gospel to those they feel are elect by appealing to the Calvinistic doctrine of election. I reject this heresy! I believe in the indiscriminate and promiscuous preaching of Christ to all without exception. Moderate Calvinists, who borrow from Arminians to affirm their common grace myth, will accuse Christians of being hyper-Calvinists who reject the myth of common grace. This should be expected. Arminians have always relied on petulant allegations to discredit Reformed preachers who unashamedly affirm election, and reject common grace. Moderates will do the same.
Personally, I believe many affirm the common grace myth because of the following: (1) they do not understand the doctrine of grace because they have not studied it, and have never been taught how it is biblically defined; (2) they are theological liberals who believe God’s grace and love is universal, or they affirm cheap grace (i.e., prevenient grace).
If you simply look to Scripture, you will see that grace is the most important doctrine in Scripture. Paul tells us why in Rom. 3:24: “Being justified freely by his grace through the redemption that is in Christ Jesus” [emphasis mine]. Don’t twist it. Don’t redefine it. And don’t ever denigrate God by referring to His grace as non-soteriological [common].
Lord have mercy.
