1 Corinthians 14:39 (NIV)
Therefore, my brothers and sisters, be eager to prophesy, and do not forbid speaking in tongues.
In the early church, the gift of tongues was a common gift which almost everyone received, as we see in the church in Corinth as an example. Paul had to give advice on how to utilize their spiritual gifts in an orderly manner in the church.
However, I can't find any specific method/instruction given in the New Testament on how to receive the gift of tongues. If I want to receive the gift of tongues, what must I do? Is there any instructions given by the early church fathers on how to receive the gift of tongues? Since the New Testament doesn't give any specific instructions on how to receive the gift of tongues, there must be some writings from the church fathers on this issue.
