9 The next day, as they were on their journey and coming near the city, Peter went up on the housetop to pray, about the sixth hour. 10 And he became hungry and desired something to eat; but while they were preparing it, he fell into a trance 11 and saw the heaven opened, and something descending, like a great sheet, let down by four corners upon the earth. 12 In it were all kinds of animals and reptiles and birds of the air. 13 And there came a voice to him, "Rise, Peter; kill and eat." 14 But Peter said, "No, Lord; for I have never eaten anything that is common or unclean." 15 And the voice came to him again a second time, "What God has cleansed, you must not call common." 16 This happened three times, and the thing was taken up at once to heaven. 17 Now while Peter was inwardly perplexed as to what the vision which he had seen might mean, behold, the men that were sent by Cornelius, having made inquiry for Simon's house, stood before the gate 18 and called out to ask whether Simon who was called Peter was lodging there.

The prejudices of Peter against the Gentiles, would have prevented his going to Cornelius, unless the Lord had prepared him for this service. To tell a Jew that God had directed those animals to be reckoned clean which were hitherto deemed unclean, was in effect saying, that the law of Moses was done away. Peter was soon made to know the meaning of it. God knows what services are before us, and how to prepare us; and we know the meaning of what he has taught us, when we find what occasion we have to make use of it.
