Putting all things right
Final judgement is God-in-Christ (John 5:26-30) putting all things right at the end of time as a part of the renewal of all things. That all things should be put right has been the burning desire of suffering humanity all through the ages.
Not only this, but God will put all things right in a way that
(a) perfectly resolves the problem of evil,
(b) perfectly suits the evil chosen by each person, and
(c) perfectly satisfies His justice and holiness.
No one will say, "that's not fair" or "I didn't feel understood."
Rather the confidence of Abraham, expressed in his rhetorical question: "Will not the judge of all the world do right?" (Genesis 18:25) - the answer to which he was certain was positive - will bring complete satisfaction.
Not because of our perfection but because of His.
