Here's a very interesting argument from Pascal, that our discomfort in life indicates our original righteousness and fall.

Pascal, Pences, 434

What, then, shall man do in this state? Shall he doubt everything? Shall he doubt whether he is awake, whether he is being pinched, or whether he is being burned? Shall he doubt whether he doubts? Shall he doubt whether he exists? We cannot go so far as that; and I lay it down as a fact that there never has been a real complete sceptic. Nature sustains our feeble reason and prevents it raving to this extent.

Shall he, then, say, on the contrary, that he certainly possesses truth—he who, when pressed ever so little, can show no title to it and is forced to let go his hold?

What a chimera, then, is man! What a novelty! What a monster, what a chaos, what a contradiction, what a prodigy! Judge of all things, imbecile worm of the earth; depositary of truth, a sink of uncertainty and error; the pride and refuse of the universe!

Who will unravel this tangle? Nature confutes the sceptics, and reason confutes the dogmatists. What, then, will you become, O men! who try to find out by your natural reason what is your true condition? You cannot avoid one of these sects, nor adhere to one of them.

Know then, proud man, what a paradox you are to yourself. Humble yourself, weak reason; be silent, foolish nature; learn that man infinitely transcends man, and learn from your Master your true condition, of which you are ignorant. Hear God.

For in fact, if man had never been corrupt, he would enjoy in his innocence both truth and happiness with assurance; and if man had always been corrupt, he would have no idea of truth or bliss. But, wretched as we are, and more so than if there were no greatness in our condition, we have an idea of happiness and can not reach it. We perceive an image of truth and possess only a lie. Incapable of absolute ignorance and of certain knowledge, we have thus been manifestly in a degree of perfection from which we have unhappily fallen.

It is, however, an astonishing thing that the mystery furthest removed from our knowledge, namely, that of the transmission of sin, should be a fact without which we can have no knowledge of ourselves. For it is beyond doubt that there is nothing which more shocks our reason than to say that the sin of the first man has rendered guilty those who, being so removed from this source, seem incapable of participation in it. This transmission does not only seem to us impossible, it seems also very unjust. For what is more contrary to the rules of our miserable justice than to damn eternally an infant incapable of will, for a sin wherein he seems to have so little a share that it was committed six thousand years before he was in existence? Certainly nothing offends us more rudely than this doctrine; and yet without this mystery, the most incomprehensible of all, we are incomprehensible to ourselves. The knot of our condition takes its twists and turns in this abyss, so that man is more inconceivable without this mystery than this mystery is inconceivable to man.

Whence it seems that God, willing to render the difficulty of our existence unintelligible to ourselves, has concealed the knot so high, or, better speaking, so low, that we are quite incapable of reaching it; so that it is not by the proud exertions of our reason, but by the simple submissions of reason, that we can truly know ourselves.

These foundations, solidly established on the inviolable authority of religion, make us know that there are two truths of faith equally certain: the one, that man, in the state of creation, or in that of grace, is raised above all nature, made like unto God and sharing in His divinity; the other, that in the state of corruption and sin, he is fallen from this state and made like unto the beasts.

These two propositions are equally sound and certain. Scripture manifestly declares this to us, when it says in some places: Deliciae meae esse cum filiis hominum. (Prov. 8:31. "And my delights were with the sons of men.") Effundam spiritum meum super omnem carnem. (Joel 2:28. "I will pour out my spirit upon all flesh.") Dii estis, (Ps. 82:6. "Ye are gods.") etc.; and in other places, Omnis caro faenum. (Is. 40:6. "All flesh is grass.") Homo assimilatus est jumentis insipientibus, et similis factus est illis. (Ps. 49:12, 13. "He is like the beasts that perish; this their way is their folly.") Dixi in corde meo de filiis hominum (Eccles. 3:18. "I said in mine heart concerning the estate of the sons of men."). 

Whence it clearly seems that man by grace is made like unto God, and a partaker in His divinity, and that without grace he is like unto the brute beasts.
