God is faithful; you were called by Him into fellowship with His Son, Jesus Christ our Lord.

But as it is written:

What eye did not see and ear did not hear,
and what never entered the human mind—
God prepared this for those who love Him.

and all were baptized into Moses in the cloud and in the sea.

For we were all baptized by one Spirit into one body—whether Jews or Greeks, whether slaves or free—and we were all made to drink of one Spirit.

In the same way, unless you use your tongue for intelligible speech, how will what is spoken be known? For you will be speaking into the air.
