Thoughts in my mind

Thou shalt not drink, gamble, go clubbing, smoke, play violent games, listen to certain genre of music...?

Most of us in life have so many questions that needs answers. Ever since I had graduated from high school till now, a lot of things have changed, friendship, family relationship, hi-bye friends and pillow-talk friends, people we know and don't know, school, even myself. I have been thrown into the world of adulthood and responsibility and expectation without realization. Many times in life I fail to have the capability to differentiate between right and wrong or good or bad and most of the times I always end up to stand in the so called 'gray area', the "not-so-right and not-so-wrong" side. There is too much dilemma in life, making it so hard to make decisions, sometime something so right can be wrong, or the other way round..

I've just been listening to someone say christians shall not drink and smoke. Some say its alright to do it as long as you don't do it excessively and without self-control. Thing is, should I take everything they said or be open-minded and take things into consideration? I was born into a christian family and I understand things about the salvation that has been given to us, the commandments, stuffs about being obedience and thankful to receive rewards in our life after death and so on and so forth. We all want to please God but many times in life we're stuck in a dilemma about making little decisions in life. For instance, one of the command from Exodus 20:1-17 says, You shall not murder. Erm, wadabout murdering virtually as in playing shooting games? Some says you can do it as long as you don't have the thoughts of killing. Sounds complicated and very hard to understand eh? How can you aim and shoot your target if you don't have the thoughts of killing the target and for game designers, how can you create a monsters/zombies/humans-killing game if you can't find the pleasure in slicing/cutting/whacking/chopping/bombing the creatures. I apologize if this doesn't make sense. I guess all the truths can be found in the bible and I believe that his words is the only thing in this world that is eternal and unchanging and we just have to search for it.
