Does God Love a Non-Christian’s Justice?

This question came from a blog of a pastor friend of mine.  He asked if we agreed or disagreed with this statement from an unnamed author:

Everyone who struggles for justice, everyone who makes just claims in unjust surroundings, is working for God’s reign, even though not a Christian.

Here was my short response:

Yes and no.

No because anything that is not from faith is sin (Rom. 14:23) and without faith it is impossible to please God (Heb. 11:6). Anything not done for the glory of God is sin and therefore even Christians can do something that is “just” and have it be sinful because it was done with a stained motive or intention

Yes because Proverbs 11:1 says, “A false balance is an abomination to the LORD, but a just weight is his delight.” So anything that is just is God’s creation. Certainly there are things non-Christians do that the Bible affirms are good and because justice and honesty and integrity are God’s design, it delights God. This is what the doctrine of common grace is all about. (Biblical example: Cyrus who didn’t know God (Isa. 45), but delivered God’s people from captivity.)
