I'll tell you...the moment I started going to bars and clubs is the moment the line became hazy (both literally and figuratively lol) between what was acceptable before God's eyes and what wasn't. During college I had done things I never thought I was capable doing...things, if presented to me years ago, wouldn't have been imaginable. Is it absolutely wrong? Technically no...will you expose yourself to unnecessarily temptation? Undoubtedly, yes. 1 Peter 5:8 says it all...
"Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour."
What I've come to understand is that the more conscious we are of the constant assault of our senses, the more adept we are in fighting temptation.
