Wow!!! What a great assignment for you to be a good witness. I'm so excited for you, I wish I had this assignment! You don't have to be judgmental or condemning, but you can still write a very powerful paper based on your convictions. Here are a few verses that might help you (there are lots more...):
Psalms 111:2 "Great are the works of the Lord; they are pondered by all who delight in them."
Proverbs 21:17 "He who loves pleasure will become poor; whoever loves wine and oil will never be rich."
Isaiah 58:13-14 "...if you call the Sabbath a delight and the Lord's holy day honorable, and if you honor it by not going your own way and not doing as you please or speaking idle words, then you will find your joy in the Lord, and I will cause you to ride on the heights of the land and to feast on the inheritance of your father Jacob."
Just remember to be kind, explain why you can't live for your own pleasure in life. You most likely won't win over your teacher, but you will be standing strong in your faith and that's more important than a good grade. Realize going into this that you are risking getting a lower grade. I had the same happen to me in my philosophy class a few years ago. We were supposed to write a paper about how miracles aren't possible. Guess what I did? I wrote a paper about how miracles are possible. He lowered my entire class grade from an A to a B because of it, but I don't care. It's his problem, not mine.
