8 Then Peter, filled with the Holy Spirit, said to them, "Rulers of the people and elders, 9 if we are questioned today because of a good deed done to someone who was sick and are asked how this man has been healed, 10 let it be known to all of you, and to all the people of Israel, that this man is standing before you in good health by the name of Jesus Christ of Nazareth, whom you crucified, whom God raised from the dead. 11 This Jesus is "the stone that was rejected by you, the builders; it has become the cornerstone.' 12 There is salvation in no one else, for there is no other name under heaven given among mortals by which we must be saved." 13 Now when they saw the boldness of Peter and John and realized that they were uneducated and ordinary men, they were amazed and recognized them as companions of Jesus. 14 When they saw the man who had been cured standing beside them, they had nothing to say in opposition.
15 So they ordered them to leave the council while they discussed the matter with one another. 16 They said, "What will we do with them? For it is obvious to all who live in Jerusalem that a notable sign has been done through them; we cannot deny it. 17 But to keep it from spreading further among the people, let us warn them to speak no more to anyone in this name." 18 So they called them and ordered them not to speak or teach at all in the name of Jesus. 19 But Peter and John answered them, "Whether it is right in God's sight to listen to you rather than to God, you must judge; 20 for we cannot keep from speaking about what we have seen and heard."

Commentary on Acts 4:5-14
(Read Acts 4:5-14)
Peter being filled with the Holy Ghost, would have all to understand, that the miracle had been wrought by the name, or power, of Jesus of Nazareth, the Messiah, whom they had crucified; and this confirmed their testimony to his resurrection from the dead, which proved him to be the Messiah. These rulers must either be saved by that Jesus whom they had crucified, or they must perish for ever. The name of Jesus is given to men of every age and nation, as that whereby alone believers are saved from the wrath to come. But when covetousness, pride, or any corrupt passion, rules within, men shut their eyes, and close their hearts, in enmity against the light; considering all as ignorant and unlearned, who desire to know nothing in comparison with Christ crucified. And the followers of Christ should act so that all who converse with them, may take knowledge that they have been with Jesus. That makes them holy, heavenly, spiritual, and cheerful, and raises them above this world.
Commentary on Acts 4:15-22
(Read Acts 4:15-22)
All the care of the rulers is, that the doctrine of Christ spread not among the people, yet they cannot say it is false or dangerous, or of any ill tendency; and they are ashamed to own the true reason; that it testifies against their hypocrisy, wickedness, and tyranny. Those who know how to put a just value upon Christ's promises, know how to put just contempt upon the world's threatenings. The apostles look with concern on perishing souls, and know they cannot escape eternal ruin but by Jesus Christ, therefore they are faithful in warning, and showing the right way. None will enjoy peace of mind, nor act uprightly, till they have learned to guide their conduct by the fixed standard of truth, and not by the shifting opinions and fancies of men. Especially beware of a vain attempt to serve two masters, God and the world; the end will be, you can serve neither fully.
