Kicking off Pslams 10 the chapter opens with a lamentation and then pronounces bad days for the wicked:

Psa 10:1  O LORD, why do you stand so far away? Why do you hide when I am in trouble?

Psa 10:2  The wicked arrogantly hunt down the poor. Let them be caught in the evil they plan for others.

Wicked people tend to prey on those who can’t defend themselves, almost animalistic type instincts like the gang of lions that ambush the grazing gazelle, or a group of gangbangers who jump the one unknowing victim.  

The Psalmist expresses frustration with God’s seeming absence and then asks God to deliver justice for the victims.  

Many times, we see the wrong things happen in the world and can have our faith challenged by these things like child death or tsunamis, but we don’t see the forest through the trees, or the big picture either.  Sometimes, these stumbling blocks are put in our path for God’s larger purpose.  We look at Job who lost everything in a whirlwind, but ended up becoming far more blessed after all his calamities than he was before, Job even spoke with God!  Even in our own lives, we run into some massive tragedy, but looking back on it, often times the tragedy opens other doors, all of this is for God’s greater purpose, that is beyond our fickle understanding.
