10:1-8 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.And when ... - "It has been remarked that from Joppa, Jonah was sent to preach to the Gentiles at Nineveh, and that from the same place Peter was sent to preach to the Gentiles at Caesarea" (Clarke). 7, 8. when the angel … was departed, he called—immediately doing as directed, and thereby showing the simplicity of his faith.

Thus on Cornelius’s side all things are disposed towards his receiving of the gospel; and the same providence, at the same time, disposes all things on Peter’s part towards his coming to publish it: for, .{ see Acts 10:9}

And when he had declared all these things unto them,.... Which he had heard and seen in the vision, and of which he gave them a particular account; partly to engage them the more cheerfully to go on the errand, and partly that they might be able to give a distinct relation of it to Peter, that so he might be moved the more to comply with the request, and come along with them:

he sent them to Joppa; perhaps not that evening, since it was at the ninth hour, or three o'clock in the afternoon, when Cornelius had the vision; and some time must be taken up in discourse with the angel, and afterwards in sending for his servants, and relating the affair to them, and giving them their proper instructions. So that it may be they did not set out till early the next morning, as seems from the following verse.
