If God sees all the bad stuff in the world, then why doesn't he do something about it?

Daily Scripture 5-15-10

Proverbs 15:3 (New International Version)

³ The eyes of the LORD are everywhere,
keeping watch on the wicked and the good.
--------------------------------------------------------------
Ponder this: God sees all the good in the world and all the evil. So why doesn't he stop the bad stuff? Poverty, Child prostitution, Murder, a lying tounge, sinful thoughts etc... Well, all the bad stuff is a manifestation of sin in the world. After Eve disobeyed God, she allowed for sin to enter into the realm of this world. Death is the greatest manifestation of sin but there is all this other 'bad' stuff that comes before death. Is there no hope for helping the world? God gave you His Spirit to do great things in this world. You are a door, or portal if you may, of God's kingdom. You loose and you bind. You have authority over all the wickedness in this world and righteousness in heaven. If we as believers would only pray, and live a life of holiness, this globe might look a bit different.
