Have you ever heard a party where everyone was there? The best music was playing, and it was blaring. Lots of hot guys and girls who are..."more then friendly", and alcohol lots of alcohol. Would you go to this party? Have you ever gone to a party like this? Did you enjoy yourself?
How do you feel when you're with a group of people who suddenly have "fun" doing things you arent comfortable doing?
Would Jesus attend this party? Actually...the answer to this last question is...he did. Jesus attended parties where alcohol and prostitutes were present. In fact the first recorded miricle of jesus was providing wine for a wedding that had run out. It may be hard for you to imagine jesus in this setting.
Well meaning christians may have painted an incomplete picture of Jesus. In emphasising how jesus never sinned and how he frowns apon sin, they might have given you the impression that he didn't hang around sinners either. But he did. Crowds constantly flocked around Jesus wherever he went. He hugged small children even when the disciples tried to shoo them away. He touched lepers. He tried to open peoples minds and free them from the restricted thinking of thier teachers. All in all, Jesus seemed like a pretty cool person to hang around.
Sure he came here on a serious mission, but that doesnt mean Jesus never had any fun or wasnt fun to be around. He made jokes, and probably laughed quite a bit. Most of the humor in the bible probably doesn't make much sence to us now because it was a different culture and a different time.
Jesus wants us to have fun. He never said you had to quit work and become a monk. He never said, "to follow me you must sit in your room and pray 24/7 and never even touch those who sin!"
The thing is, Jesus wants us to get out of our little holes and have fun, make a difference, and do the best we can to show who Jesus is thorough the way we live. Everything you do can be for God. And guess what, thats the secret. Thats the way you can keep from sinning.
If your first love is God you wont be doing the things he says arent a good idea. Thats why we go out to help people (on top of loving them). Thats supposed to be the reason a christian does anything. Because we love God and want to please him.
