That is what most Christians covertly hope for.
And it's a realistic hope to strive for. Because such a hope is for a world that is not 'wholly happy', nor should we hope for a world 'without suffering, disease, decay and death'. Such is impossible in this mortal earthly life; impossible because it is Not what this world is For.
(Hence not just impossible, but undesirable - a negation of what our lives are properly about.)
But I do hope for a world (my life, this actual world) as-wholly-as-possible meaningful and purposive; a world of experienced-relationships with God, Jesus Christ and the Holy Ghost...
A world where the spirit is acknowledged as really-real...
A world where (as many as possible) lives are lived in expectation of Heavenly resurrected life...
A world where we each aim to experience and think and learn; where we strive consciously to choose that which is Good.
All that is quite possible - if we want it.
Not as a 100% permanent achievement - because this world is not made to be permanent, nor are our lives intended to be 100% anything - we are, after all, here to learn: change is part of the structure.
But it is possible that such a world as I describe can be our conscious, recurrent, hourly aim.
(Of course we will keep failing. It doesn't matter - ultimately. Repenting our failures, and trying-again; we will learn. And such learning - unlike human memory - is eternal.)
And that is what most matters.
We should not be satisfied with less than an Enchanted Christianity.
