Romans 1:18
For (God does not overlook sin and) the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who in their wickedness suppress and stifle the truth.

Seeing wicked people prevailing in the world will be frustrating and stressful. However, they will not prevail against God. We cannot give up hope because that is what the devil wants. We must stand in faith and on the Word until God brings the answer. We are the barrier that prays God down from heaven to bring righteous order and truth back to earth.
