Acts 10:44-47
While Peter was still speaking these things, the holy
Spirit fell upon all who were listening to the word. The
circumcised believers who had accompanied Peter
were astounded that the gift of the holy Spirit should
have been poured out on the Gentiles also, for they
could hear them speaking in tongues and glorifying God.
Then Peter responded, "Can anyone withhold the water
for baptizing these people, who have received the holy
Spirit even as we have?"
Titus 3:5
... not because of any righteous deeds we had done but
because of his mercy, he saved us through the bath of
rebirth (baptism) and renewal by the holy Spirit.
