Legalism??

Legalistic?.... I wouldn't say that trying to live a life that is righteous for God is being legalistic. I wouldn't say that trying to keep your standards high as to make sure that you have no question of whether its sin or not is legalistic... i would say forcing your beliefs on the people around you is... but where do you personally draw the line?... its sad that on a Bible college campus you see pics of people you konw chugging down cans of beer, your hear about the pipes that have been bought or passed around, you see immodest clothing, and many other things... it's sad. I don't believe that drinking is a sin... but what's the point of drinking?? What's the motives behind the drink? Not just your motives, but the motives of those who made the beer?... It's not just how you interpret the lyrics, but how the artist meant for them to be interpreted, ya know... but it sucks even more when someone tells another believer, hey I think what you're doing might be wrong, and that person just brushes it of with the 'ole "you're being legalistic" phrase. I understand that we as New Testament believers are under the Law of Liberty...but does that mean we have the liberty to do whatever we want?... You smoke the weed, I'll go have sex... I mean come on! whats the difference?! It doesn't matter about just saving yourself for marriage. It's a matter of being pure in the sight of God. My outlook on the whole issue is this... I wan't to be as close to blameless as I possibly can be. I want to live a holy life for my Lord. I dont want to live on the fence, seeing how close I can get. That's not the point of the Christian's life! The point of the Christian's life is to be Christ to those around them! Legalism... you show me someone you consider to be legalistic, and I'll show you someone who whole-heartedly desires to live a godly life. I'm not saying that legalism is right, I'm just wondering if we're really trying to live lives wholly devoted to God? (I want to clarify that overall this school is great, but i have made a few observations that I addressed here).
