It was Jesus who said, "The last will be first, and the first will be last." (Matthew 20.16.) How can this be fair? Though life truly seems unfair, eternal life and eternal condemnation will set everything straight in the end. The short span of our earthly life is nothing (zero) when compared to timeless eternity. In heaven, every sufferings we endured on earth will have been forgotten, In hell, all worldly enjoyment we had wouldn't have meant anything. Be wise and live for eternity, never for our earthly life.
