Question

Unless you're lifting for bodybuilding (which has its own specific rules about when and how to workout), you could go to the gym and workout even if you're still sore from your last workout session. Actually, keeping your body moving can help provide some relief from your soreness. Keep in mind to do an extended warm-up to loosen up your muscles. Stretching before and after your workout will also help release some tension. If your soreness is really bothering you than doing a lighter workout will still be beneficial while not overtaxing the sore muscles. Also, if you feel pain during your workout, more than just slight soreness, then you should take another day of rest before continuing with your workout goals.
