At Caesarea there was a man named Cornelius, a centurion in what was known as the Italian Regiment. He and all his family were devout and God-fearing; he gave generously to those in need and prayed to God regularly. One day at about three in the afternoon he had a vision. He distinctly saw an angel of God, who came to him and said, "Cornelius!"
Cornelius stared at him in fear. "What is it, Lord?" he asked.
The angel answered, "Your prayers and gifts to the poor have come up as a memorial offering before God. Now send men to Joppa to bring back a man named Simon who is called Peter. He is staying with Simon the tanner, whose house is by the sea."
This is the place God showed Peter that the Gospel is meant for everyone - Jews and Gentiles alike.
This is the place where God clearly indicates that He shows no favouritism, "but accepts from every nation the one who fears him and does what is right." (Acts 10:35).
This is the place where the world changed, where salvation is available to the world through what God has done in Jesus Christ.
