Having arrived at Cornelius’s house in Caesarea, Peter now begins to preach the Gospel to Cornelius’s household. He begins by defending his actions in sharing this message with the Gentiles - reflecting on the fact that God does not show partiality in His dealings with men. He then preaches the Word to the Gentiles there, building on the knowledge of Christ that Cornelius’s household already had and then moving to facts that they may have been less familiar with but that were essential to the Gospel (e.g. the resurrection). Through the sermon that Peter delivers, the Holy Spirit then came upon the Gentiles as He had upon the Jews on the Day of Pentecost, granting them salvation.
We draw out useful points of application throughout this account, and are further encouraged to seek God for the infilling of His Holy Spirit as we seek to serve Him here.
