People tend to drink more at night or in dark places because deep inside they know it is wrong. And there is often a progression from drinking to carousing, which later leads to sexual promiscuity. Many young men drink at parties so they can encourage their date to get drunk and loose. The devil is like a dog who is tied up in someone's front yard. He has limited power, as seen by the path he has worn on the grass.
Some people see how close they can get to sin without stepping into the path of the dog.
But suppose the dog is pretty smart. He lunges only part of the way out, and the next time not as far. This lures us into believing that we can get closer and still not get caught. People are always telling us what is a sin and what is not a sin. These are the real issues we need to address when talking about alcohol.
