While it probably doesn't suggest that we have no role in what is often - aptly or not - referred to as 'social justice,' it is God who has to bring about that justice. We may still have some active role, but we're not going to be the one calling the shots, or guaranteeing the results.
According to their deeds, so He will repay, wrath to His adversaries, recompense to His enemies; to the coastlands He will make recompense. So they will fear the name of the Lord from the west and His glory from the rising of the sun, for He will come like a rushing stream which the wind of the Lord drives.
Isaiah 59:18-19 NASB
So, what is our primary role?
“As for Me, this is My covenant with them,” says the Lord: “My Spirit which is upon you, and My words which I have put in your mouth shall not depart from your mouth, nor from the mouth of your offspring, nor from the mouth of your offspring’s offspring,” says the Lord, “from now and forever.”
Isaiah 59:21 NASB
Our primary role is focus on becoming who God desires us to be (which will/must flow into action), and train our children right. In particular, focus on God's Word so that His Spirit has something to remind us of. However, I might add, let's not do it ripping verses out of context so that they develop a life of their own that was never intended, even in a way that may actually falsify them. Rather, let's learn God's Word knowing full well the context of the scriptures we're memorizing. Maybe we even need to do it by memorizing entire chapters.
