1CO 14:2

2 [I say that] because those who speak messages that come directly from God [are speaking in languages that they and the other believers in the congregation know, and so] they are able to strengthen them [spiritually] and to encourage and comfort them. But those who speak in languages [MTY] [that they have not learned] are not speaking to people. Instead, they are [only] speaking to God. No one understands them. By [the power/guidance of God’s] Spirit (OR, From within [their own] spirit) they speak things that others do not know.
