Charismatic Churches generally believe that the gifts of the Holy Spirit described in the New Testament are all still active today. Specifically for charismatics, this includes the gifts of speaking in tongues, healing, words of knowledge, and prophecy. Charismatics will freely exercise these gifts in many different church contexts, praying in tongues during a worship gathering, holding special services of healing for people in the congregation, etc, and this behavior is largely similar to the pentecostals; however, charismatics believe generally that these "sign gifts" are a privilege for believers but not necessarily expected of believers. Some believers have them and some don't. Some churches may exercise them all the time and others only rarely. Many evangelical churches may share this last belief, but charismatic churches would encourage both private and public expressions of these gifts.
