Life is not fair. Thus goes the lament.
Evil people prosper. There is no justice.
That is the lament of those who tag it all with this question:
The psalmist cried this often-cried cry and then,
"But when I thought how to understand this,
it seemed to me a wearisome task,
until I went into the sanctuary of God;
then I discerned their end." (Psalm 73:16-17 ESV)
Until he went before God to gain perspective - the perspective of the whole of their lives, the whole of his life, and the vastness of God's purposes.
Some insights are simply unattainable outside the presence of God.
