3 About the ninth hour of the day he saw clearly in a vision an angel of God coming in and saying to him, "Cornelius!" 4 And when he observed him, he was afraid, and said, "What is it, lord?" So he said to him, "Your prayers and your alms have come up for a memorial before God. 5 Now send men to Joppa, and send for Simon whose surname is Peter. 6 He is lodging with Simon, a tanner, whose house is by the sea. He will tell you what you must do." 7 And when the angel who spoke to him had departed, Cornelius called two of his household servants and a devout soldier from among those who waited on him continually.

Hitherto none had been baptized into the Christian church but Jews, Samaritans, and those converts who had been circumcised and observed the ceremonial law; but now the Gentiles were to be called to partake all the privileges of God's people, without first becoming Jews. Pure and undefiled religion is sometimes found where we least expect it. Wherever the fear of God rules in the heart, it will appear both in works of charity and of piety, neither will excuse from the other. Doubtless Cornelius had true faith in God's word, as far as he understood it, though not as yet clear faith in Christ. This was the work of the Spirit of God, through the mediation of Jesus, even before Cornelius knew him, as is the case with us all when we, who before were dead in sin, are made alive. Through Christ also his prayers and alms were accepted, which otherwise would have been rejected. Without dispute or delay Cornelius was obedient to the heavenly vision. In the affairs of our souls, let us not lose time.
