Cornelius was taught about Jesus AFTER God had already accepted him.
1 There was a certain man in Caesarea called Cornelius, a centurion of the band called the Italian band,
• • •
3 He saw in a avision evidently about the ninth hour of the day an cangel of God coming in to him, and saying unto him, Cornelius.
• • •
7 And when the angel which spake unto Cornelius was departed, he called two of his household servants, and a devout soldier of them that waited on him continually;
• • •
17 Now while Peter doubted in himself what this vision which he had seen should mean, behold, the men which were sent from Cornelius had made enquiry for Simon’s house, and stood before the gate,
• • •
21 Then Peter went down to the men which were sent unto him from Cornelius; and said, Behold, I am he whom ye seek: what is the cause wherefore ye are come?
22 And they said, Cornelius the centurion, a just man, and one that feareth God, and of good report among all the nation of the Jews, was awarned from God by an holy angel to send for thee into his house, and to hear words of thee.
• • •
24 And the morrow after they entered into Caesarea. And Cornelius waited for them, and had called together his kinsmen and near friends.
25 And as Peter was coming in, Cornelius met him, and fell down at his feet, and worshipped him.
• • •
30 And Cornelius said, Four days ago I was afasting until this hour; and at the ninth hour I prayed in my house, and, behold, a bman stood before me in bright clothing,
31 And said, Cornelius, thy prayer is heard, and thine alms are had in remembrance in the sight of God.
I believe being visited by an angel counts as being taught about the Gospel or given a particular knowledge of God and his dealings with men. The scripture also says he was “one that feareth God”. It suggests that he had previous knowledge as well.
Again, I refer to those who do not receive the word of God because it was never preached to them. Are they saved in your estimation? What happens to them?
