1 Corinthians 14:36-39

Did the word of the Lord originate from you [Corinthians], or has it come to you only [so that you know best what God requires]? If anyone thinks and claims that he is a prophet [a true spokesman for God] or spiritually astute [filled with and energized by the Holy Spirit], let him recognize that the things which I write to you are the Lord’s commandment. If anyone does not recognize this [that it is a command of the Lord], he is not recognized [by God]. Therefore, believers, desire earnestly to prophesy [to foretell the future, to speak a new message from God to the people], and do not forbid speaking in unknown tongues.
