I can still call myself a Christian even though I've gotten drunk and gambled before right?

Both things are rare. The last time I got drunk was a couple of weeks ago when I went to Reno with my bowling league. It was on the bus ride up and I just got carried away. First time I experienced the bus ride to Reno. Last time though before that was 4 years ago. Last time I gambled aside from a couple of weeks ago was 2006, so 5 years ago.
