Hard verses of Psalm 21

In some of the other 'Difficult Verses' passages it has been easy for me to see God as a judge to account for their difficult nature. In those passages, God is righteous and his punishment for the wicked is analogous to a judge. But, in Psalm 22 this doesn't appear to be the case.

"At the time of your appearing you will make them like a fiery furnace. In his wrath the Lord will swallow them up, and his fire will consume them. You will destroy their descendants from the earth, their posterity from mankind. Though they plot evil against you and devise wicked schemes, they cannot succeed; for you will make them turn their backs when you aim at them with drawn bow" (Psalm 21:9-12).

Here I see something different then God the judge. Here it seems like I see God the warrior. God is called the protector and refuge throughout the Psalms. But in chapter 21 we see God going on the offensive. But, even in this mode as the warrior, God is still acting on his ultimate righteousness. He is taking out the enemies of God and His people. He is still protecting. While I haven't quite come to a conclusion on this passage, what I do know is that God is not a passive God. He is active and involved in the lives of His people. It is His bow that will make the enemies of his people turn back. It is through the victories that God gave that has made his people glorious. It is through God's gift that has given them splendor and majesty. It's hard not to see God as Zeus wielding a thunderbolt to protect his people in this passage. I have to fight that imagery because I know it's inaccurate. But, my inaccuracies don't take away from God's glory or person. I simply have to know that God's righteousness demands action and that He is not afraid or unwilling to act.
