Cornelius was a leader of those hated Roman soldiers. But Acts 10 describes him as one "who feared God with all his household, and gave many alms to the Jewish people and prayed to God continually". Hmm... Surprising!
Evidently he was seeking God because the Lord went to great lengths (sent two angels, one vision, three messengers, and then Peter and friends back to Caesarea) to cross that great culture wall and get the truth to this God-fearing Gentile. And it was sure a set up because "While Peter was still speaking these words, the Holy Spirit fell upon all those who were listening to the message".
The result was that a whole family was added to God's kingdom ("Surely no one can refuse the water for these to be baptized who have received the Holy Spirit just as we did, can he?" And he ordered them to be baptized in the name of Jesus Christ").
And wonderful for us - the door was opened for the good news to be spread to the Gentiles. God will go way out of His "normal" path to bring His people back to Him.
Thank you. Lord
