Job 38:16 says, Hast thou entered into the springs of the sea? or hast thou walked in the search of the depth?  God continues to ask Job if he thought he had the power and ability that God did.  I believe that if we are going to question God's right to act in the world that we need to know more and be more powerful than He is.  Otherwise, we need to accept that as God's followers He will never bring harm to us.  This is what God was addressing with Job.  Verse seventeen asks, Have the gates of death been opened unto thee? or hast thou seen the doors of the shadow of death?  Only God has power over death.  As followers of Christ, we may know that we have everlasting life, but we certainly do not understand everything that happens between our death and resurrection.  God alone can bring resurrection to anyone.  Job should have been content knowing this instead of questioning God, and so should we.  Verse eighteen asks, Hast thou perceived the breadth of the earth? declare if thou knowest it all.  In Job's day, they certainly did not know the breadth of the earth.  Today, with satellites we may say that we can answer that question, but we cannot claim to know everything there is to know about the earth.  We can never understood all the ways that the world works, much less the universe.  We can never go anywhere that God isn't already there.   Verse nineteen asks, Where is the way where light dwelleth? and as for darkness, where is the place thereof,  Though we may understand that the day is going to be light and the night is going to be dark, where do the light and darkness come from?  We can answer that the light comes from the sun and the light at night from the moon, but where did they come from and what causes them to be separated in such a precise manner?  I believe that God was reminding Job that he knew that God alone had this power, and that therefore Job had no right to question or doubt God.  Neither do we today.  Verse twenty says, That thou shouldest take it to the bound thereof, and that thou shouldest know the paths to the house thereof?  God asked Job if he knew the boundaries of the heavens.  The universe has been hurtling through space since creation and has never reached an end.  We may speak of going to Mars, but that is but a tiny step in the vastness of the universe.  Verse twenty-one asks,  Knowest thou it, because thou wast then born? or because the number of thy days is great?  God continues to question Job about his ability to understand everything in creation.  God asked if Job was there at the beginning of time or if he had lived long enough to explain creation.  As followers of Christ, the first thing we must acknowledge iris our limited understanding.  Verse twenty-two asks, Hast thou entered into the treasures of the snow? or hast thou seen the treasures of the hail,  We may not view snow, or hail especially, to be a treasure, but we also can not control them.  Verse twenty-three states, Which I have reserved against the time of trouble, against the day of battle and war?  Then verse twenty-four asks, By what way is the light parted, which scattereth the east wind upon the earth?  God does indeed have power over the elements, and does part the night and day.  If God were to choose to destroy the world, He has it within His ability to do so.  God was reminding Job of God's power and of Job's need to just rely on God no matter what.
