For some reason, there are Christians that have a problem with labeling God's universal love, mercy, kindness, benevolence, or longsuffering as common "grace". Instead of dealing with their underlying conceptual problem that God can have a benevolent or loving disposition toward the non-elect, they quibble over the use of the term "grace" to describe it. If grace is at least, in some instances, God's favor shown to the ill-deserving, then it seems easy, on systematic theological grounds, to call his universal love common "grace". However, you know how the "just give me a verse" crowd is, so here are a couple for them:
NKJ Nehemiah 9:17 They refused to obey, And they were not mindful of Your wonders That You did among them. But they hardened their necks, And in their rebellion They appointed a leader To return to their bondage. But You are God, Ready to pardon, Gracious and merciful, Slow to anger, Abundant in kindness, And did not forsake them.
NKJ Nehemiah 9:31 Nevertheless in Your great mercy You did not utterly consume them nor forsake them; For You are God, gracious and merciful.
In other words, God was gracious or favorable towards these disobedient people, some of which, no doubt, were made up of the non-elect.
One might also use this verse:
NKJ Jeremiah 16:13 'Therefore I will cast you out of this land into a land that you do not know, neither you nor your fathers; and there you shall serve other gods day and night, where I will not show you favor.'
The term "favor" is the same term used in the Hebrew for God's gracious disposition [see the New International Dictionary of Old Testament Theology & Exegesis (Zondervan, 1997), 2:203-206.]. So, whereas the Israelites formerly had God's "favor" in their land, they will be cast out for their disobedience and no longer be shown favor (i.e. grace).
Here are more verses:
NKJ Isaiah 26:10 Let grace be shown to the wicked, Yet he will not learn righteousness; In the land of uprightness he will deal unjustly, And will not behold the majesty of the LORD.
God showed favor/lovingkindness/mercy and love to all of Israel, not just to the elect within Israel.
NKJ Psalm 85:1 To the Chief Musician. A Psalm of the sons of Korah. Lord, You have been favorable to Your land; You have brought back the captivity of Jacob.
NKJ Isaiah 60:10 " The sons of foreigners shall build up your walls, And their kings shall minister to you; For in My wrath I struck you, But in My favor I have had mercy on you.
NKJ Jeremiah 16:5 For thus says the LORD: "Do not enter the house of mourning, nor go to lament or bemoan them; for I have taken away My peace from this people," says the LORD, "lovingkindness and mercies.
