I like the fact that Cornelius invited his family and close friends over to his house so that they too can hear what God commanded Peter to share with him. This says something about Cornelius. He wanted those who were dear to him to be a part of something very important–something that could change lives.
If the Lord were to ask us to invite a pastor over to tell us the things we need to know, how many people we would invite? What do we say to them to convince them to come over? Did Cornelius’ have to convince his relatives and friends to join him? I don’t think so. Based on the kind of man he was, they would have had no problem accepting his invitation. I’m sure they were happy they went. They got to hear a powerful sermon about Jesus. They learned that God doesn’t play favorites and everyone who fears Him and do what is right and pleasing in His sight are accepted by Him. They heard about the ministry, death and resurrection of Jesus. They had the assurance that whoever believes in Jesus will receive remission of sins.
While Peter was still speaking the Holy Spirit fell upon Cornelius and those who were with him. They began to speak in tongues and glorify God. Right away Peter made arrangements for them to be baptized. What an incredible experience this must have been for Cornelius and his household. They received Jesus and were baptized with the Holy Spirit. God demonstrated here that His grace is for everyone.
