Job is not finding a basis for his faith here.  He is looking at the end of the road instead of the joy ahead.  His friends have been beating him down and he is not much kinder to himself.

Man that is born of a woman is of few days and full of trouble.  He cometh forth like a flower, and is cut down: he fleeth also as a shadow, and continueth not.  And doth thou open thine eyes upon such an one, and bringest me into judgment with thee?  Who can bring a clean thing out of an unclean? not one.  Seeing his days are determined, the number of his months are with thee, thou hast appointed his bounds that he cannot pass;  Job 14:1-5

After rebuking his friends, Job is still lost in his despair.  He is aware of his mortality and how short are the days of a lifetime.  If God has decided the time of our end our days are already numbered to God.

Turn from him, that he may rest, till he shall accomplish, as an hireling, his day.  For there is hope of a tree, if it be cut down, that it will sprout again, and that the tender branch thereof will not cease.  Though the root thereof wax old in the earth, and the stock thereof die in the ground;  Yet through the scent of water it will bud, and bring forth boughs like a plant.  But man dieth, and wasteth away: yea, man giveth up the ghost, and where is he?  Job 14:6-10

Even a tree that was cut down might find water and still return to life.  But where does man go if his days are ended?  Job is not aware of the eternal promises of God it would seem here.

As the waters fail from the sea, and the flood decayeth and drieth up:  So man lieth down, and riseth not: till the heavens be no more, they shall not awake, nor be raised out of their sleep.  O that thou wouldest hide me in the grave, that thou wouldest keep me secret, until thy wrath be past, that thou wouldest appoint me a set time, and remember me!  If a man die, shall he live again? all the days of my appointed time will I wait, till my change come.  Thou shalt call, and I will answer thee: thou wilt have a desire to the work of thine hands.  Job 14:11-15

Job expects death to be the end of a man’s being, without hope.  He may wish to be hidden in death away from the misery of this trial in his life.  He asks if a man shall die and still live again.  He seems willing to endure his time to live and hopes for the death to end his misery.  He is expecting God to call him to the grave.

For now thou numberest my steps: dost thou not watch over my sin?  My transgression is sealed up in a bag, and thou sewest up mine iniquity.  And surely the mountains falling cometh to nought, and the rock is removed out of his place.  The waters wear the stones: thou washest away the things which grow out of the dust of the earth; and thou destroyest the hope of man.  Thou prevailest for ever against him, and he passeth: thou changest his countenance, and sendest him away.  His sons come to honour, and he knoweth it not; and they are brought low, but he perceiveth it not of them.  But his flesh upon him shall have pain, and his soul within him shall mourn. Job 14:16-22

Job knows that his sins are in the bag, as if he knows repentance has removed his guilt.  As mountains and rocks fall to erosion, God wears down the days of man.  A man will not see the honor his sons earn, and he will be buried with no more part except the pain of passing.

I have suffered loss of family, health, and prosperity.  As a senior I would struggle to live without the assurance I have from my relationship with a savior who answers.  Job has not lived with the instruction and encouragement that Yeshua delivered to Israel in the New Testament.  Still he is willing to live with his fate without cursing God.  He doesn’t understand his suffering, but he lives with it.
