Go, doubting nothing. The Scripture useth this word often, when it will express of what sort the obedience of faith ought to be. So Paul, in the fourth chapter to the Romans, (Romans 4:19,) when as he commendeth the faith of Abraham, saith, That he doubted not when as the Lord promised him seed, being now aged and past hope of children. And in the fourteenth, (Romans 14:23,) in treating of meats, he condemneth doubting consciences. And it is properly to reason on both sides, (as they say,) when as we are carried hither and thither by course, by gathering contrary reasons. But we must not follow God with a doubtful and wavering, but with a quiet and constant mind. In sum, the Lord will have us to attribute so much to him, that when we hear him we dispute no longer what we have need to do, but that we set down for a certainty, that that must be done which he commandeth. And surely it is meet that his will should show us the way, when all clouds are driven away, and that it should subdue all our senses unto it, unto willing obedience, all reasoning [disputation] being broken off; which is also better gathered by the next text. For the reason is added, why it is not lawful for Peter to suspend his judgment in an uncertain matter, because God is the author of the business; because it is as much as if it should be said, that we ought to be content with the beck of God alone, that we may obey his commandment. And hereby are we also admonished that men's consciences shall by no other means be quiet, that they safely do that which they do, than when being taught by the Word of God, they determine that they do nothing without his commandment and conduct.

Arise, therefore, and get thee down,.... From the top of the house where he was:
and go with them; the three men, to Caesarea
doubting nothing; whether it is right or wrong, lawful or unlawful, to go with them, because not Jews, but uncircumcised Gentiles, laying aside all such Jewish scruples:
for I have sent them: the Spirit of God is said to do what Cornelius did at his instigation and direction, signified by an angel he sent to him, Acts 10:5.
