Job 28:1 says, Surely there is a vein for the silver, and a place for gold where they fine it.  Job seems to have moved on from his discussion of the concept of his suffering being due to sin to the nature of people attempting to gain the riches of this world.  Job said that there were indeed riches in this world, like silver and gold.  They are hard to find, and are therefore seen as more valuable.  Still, we must acknowledge that their value is assigned by man, and we cannot give them an everlasting value.  Only the things done for God have an everlasting value.  Verse two states, Iron is taken out of the earth, and brass is molten out of the stone.  Though not as highly valued as gold and silver, iron and brass have more practical uses in the world.  Still, all of these metals must be worked for.  People are willing to take great risks to remove these metals from the earth, because they are usually hidden deep in the earth.  I believe that we as followers of Christ should be just as diligent in seeking God's will in our lives, because that is where our real treasure lies.  Verse three says, He setteth an end to darkness, and searcheth out all perfection: the stones of darkness, and the shadow of death.  Job said that people would do whatever was necessary to obtain the riches of this world.  When mining for silver and gold, darkness is set aside by artificial light while in the mines.  We, as followers of Christ should be as willing to work for His glory, while living in the true light.  Verse four states, The flood breaketh out from the inhabitant; even the waters forgotten of the foot: they are dried up, they are gone away from men.  Matthew Henry says this means that people are able to divert even the waters to attain the precious metals and gems of the world.  We should be willing to work just a hard to uncover the riches of God's word.  Though salvation is free, we are still expected to work to advance God's kingdom.  Verse five says, As for the earth, out of it cometh bread: and under it is turned up as it were fire.  I believe that Job was saying that though we might value gold and silver more, that we really should be thankful for the food provided by the earth.  I believe we need to be thankful to God for meeting our needs and not just for bringing us riches.  Verse six states, The stones of it are the place of sapphires: and it hath dust of gold.  Again, we know that there are riches to be found in the earth.  People will go to great extremes to attain these riches, which are all but another part of God's creation and are temporary in their value.  Verse seven says, There is a path which no fowl knoweth, and which the vulture’s eye hath not seen:  Then verse eight states, The lion’s whelps have not trodden it, nor the fierce lion passed by it.  I believe that Job was saying that these riches were hidden to even the sharp eye of the vulture and were not found by be beasts of the earth, but that men could dig them out of the earth.  Verse nine states, He putteth forth his hand upon the rock; he overturneth the mountains by the roots.  This verse, and the next two, speak of the efforts that people will go to in obtaining the precious metals, silver and gold, and jewels from the earth.  Verse ten says, He cutteth out rivers among the rocks; and his eye seeth every precious thing.  Then verse eleven concludes, He bindeth the floods from overflowing; and the thing that is hid bringeth he forth to light. Job said that people would move mountains or divert rivers to gain the riches of the earth.  I believe that the Implication is that people put more effort in obtaining the riches of the earth, which really have an arbitrary value, than they put into following God's will, which has an everlasting value.
