4:12 Neither is there salvation in any other: for there is none other {f} name {g} under heaven {h} given among men, whereby we must be saved.
(f) There is no other man, or no other power and authority at all; and this kind of speech was common among the Jews, and arose from this, that when we are in danger we call upon those at whose hands we look for help.
(g) Anywhere: and this shows us the largeness of Christ's kingdom.
(h) Of God.
4:12 Neither is there salvation in any other. No other Savior but Jesus; no salvation if his is rejected; no other name or power to save from destruction, unless he is accepted. Why, then, should men invoke the Virgin, or the saints?
4:12 There is no other name whereby we must he saved - The apostle uses a beautiful gradation, from the temporal deliverance which had been wrought for the poor cripple, by the power of Christ, to that of a much nobler and more important kind, which is wrought by Christ for impotent and sinful souls. He therein follows the admirable custom of his great Lord and Master, who continually took occasion from earthly to speak of spiritual things.
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.
