This passage

This passage has been coming up so often latly for me and I dont know why.  It has come up a few times in class, and I should say in DIFFERENT classes which are not related.  It has come up on sites while searching for other classes, it has come up (more then once) in conversations and talking with people...Yah Its out of Romans 12 and I am not sure how I feel about it...OH and its also the theme for IMPACT this weekend-Romans 12:1-2.  So God...my question for you is...what are you trying to tell me? teach me?
Read it, let me know what you think of it
(The parts in Bold...are the parts I struggle with...and the parts which are bolded and italicized are random thoughts/questions I have of that text)

Romans 12

Living Sacrifices

 1Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God—this is your spiritual act of worship. 2Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is—his good, pleasing and perfect will.

 3For by the grace given me I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the measure of faith God has given you. 4Just as each of us has one body with many members, and these members do not all have the same function, 5so in Christ we who are many form one body, and each member belongs to all the others. 6We have different gifts, according to the grace given us. If a man's gift is prophesying, let him use it in proportion to his^[b]faith. 7If it is serving, let him serve; if it is teaching, let him teach; 8if it is encouraging, let him encourage; if it is contributing to the needs of others, let him give generously; if it is leadership, let him govern diligently; if it is showing mercy, let him do it cheerfully.

Love

 9Love must be sincere. Hate what is evil; cling to what is good. 10Be devoted to one another in brotherly love. Honor one another above yourselves. 11Never be lacking in zeal, but keep your spiritual fervor, serving the Lord. 12Be joyful in hope, patient in affliction, faithful in prayer. 13Share with God's people who are in need. Practice hospitality.

 14Bless those who persecute you; bless and do not curse. 15Rejoice with those who rejoice; mourn with those who mourn. 16Live in harmony with one another. Do not be proud, but be willing to associate with people of low position.Do not be conceited.

 17Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everybody. 18If it is possible, as far as it depends on you, live at peace with everyone. 19 Do not take revenge, my friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay,"says the Lord. (do we ever fully get the justice we need and deserve if someone has wronged us?  Is God's wrath the legal side of it? or is that just our human way of dealing with things? Will we see God's wrath/revenge then on those?)
 20 On the contrary:
   "If your enemy is hungry, feed him;
      if he is thirsty, give him something to drink.
   In doing this, you will heap burning coals on his head."
21Do not be overcome by evil, but overcome evil with good. (why is it so much easier to over come evil with evil? how does Justice fit into it all? Why is this SO hard?)

Did God Create Evil?  Did GOd create Hell?  How do those two aspects tie into it all?  again, some random thoughts, but yet at the same time, not so random....theres perpahs and meaning behind these questions...Yah God's making  me think these days, and its acutally kind of scary....
