A common theme through the Psalms is why do the wicked get away with all the evil they do. It's a good question. The easy answer is that we live in a fallen, evil world and the prince of this world, the prince of darkness has been allowed to work. The difficult answer is explaining why God seems to be far off. "Lord, why do You stand so far away? Why do you hide in times of trouble?" vs. 1
I like verse 14 "But You Yourself have seen trouble and grief, observing it in order to take the matter into Your hands. The helpless entrusts himself to You."
"Lord, You have heard the desire of the humble;
You will strengthen their hearts.
You will listen carefully,
doing justice for the fatherless and the oppressed
so that men of the earth may terrify them no more." 17-18 HCSB
