Because you say, I am rich, and increased with goods, and have need of nothing; and know not that you are wretched, and miserable, and poor, and blind, and naked: (Revelation 3:17).
The verse context is Jesus speaking through Apostle John in His revelation to the 7 churches. Jesus is harshest to the church at Laodicea. Laodicea at that time was a thriving metropolis in the Lycus valley. It had merchants selling and producing goods. The guild system (a trade association promoting unity among craftsmen) in this area was strong, most strongly in Thyatira but guilds existed also in Laodicea. Guilds are like the Labor Unions of old, when unions were at their strongest, to help each other in maintaining standards adn for mutual aid, and influence. There was a famous medical center to which students and patients arrived from all around. Laodicea was a banking center, finance was the anchor of its commercial center.
Laodicea had it all. It had "social justice" in its nearly perfect sense.
And according to Jesus, it failed.
Social Justice will always fail.
They [Laodiceans] really had not what was necessary to meet the actual needs of their nature, and, therefore, they were poor. Their worldly property could not meet the needs of their souls; and, with all their pretensions to piety, they had not religion enough to meet the necessities of their nature when calamities should come, or when death should approach; and they were, therefore, in the strictest sense of the term, poor. Barnes' Notes on the BibleJesus said the Laodiceans were rich but still poor. The only cure for poverty, despair, inequality, and injustice is the Gospel. The more that Social Justice Warriors take their eyes off the Gospel and onto temporal problems and fixes, the more they will fail. The more they argue that this is what the world needs, the more they will fail. What we are here on earth to speak for first and foremost, is the soul problem, not the social problem.
Alexander the coppersmith and Demetrius the silversmith were in guilds. (Acts 19:25–27)
PS: Of course we help the poor, of course we establish orphanages and hospitals and of course we have concerns for the disadvantaged. But you get the point of the essay, I hope. If legitimately not, ask me in the comments and I'll happily clarify.
