Social justice without an eternal anchor in futile.
If justice is real, then eternity must exist.
If there is no eternity, then there is no true justice.
We may gain slightly better circumstances in our life, but gaining true justice in life is exceedingly rare, if it even occurs at all. Yet we all long for justice, hope for it, believe it is a real thing, and fight for it. So if we do not gain it in this life, then we must acknowledge the possibility of its fulfillment in the next. This also means that “the next life” will not be in this world, as some propose.
