Confusion takes place when one has not been taught that there is a distinction between
receiving the Holy Ghost with the evidence of speaking in tongues, and receiving Spiritual Gifts for edification of the church. They are two entirely different things:
One-Each person must receive the Holy Ghost this is the promised gift. (Acts 2, 8:12-17, 10:44-48, 19:2-6) In each of these cases the Holy Ghost poured into the human body of the individuals. The evidence that this occurred was the person began speaking in tongues. Read Paul's comment in Acts 19: have you received the Holy Ghost since you believed? A person cannot be born again without having the Holy Ghost/Spirit take up residence in their body.
Two- Born again individuals receive Spiritual gifts (prophecy, word of knowledge, tongues and/or interpretation, etc.) distributed to them by the Holy Ghost that dwells inside their human body. (1 Cor. 12 and 14)
