In the bible in Acts chapter 10
1- (Chapter 10-1) An angel appeared to Cornelius and told him to send Peter
2- (Chapter 10-15) Peter received a vision in which he learned that the Gentiles would also receive the Gospel.
3- (Chapter 10-24) Cornelius gathered family and friends to listen to Peter's message.
4- (Chapter 10-37) Peter preached Christ as the risen and exalted Lord.
5- (Chapter 10-44) Cornelius and all who believed with him received the Holy Spirit.
In events chapter 10 tells us how Peter is sent to Cornelius by God to speak of the gospel and as a cornelius in the company of his family they believed and were baptized by the Holy Spirit
