2:19 I will shew wonders in heaven. Peter not only quotes that part of the prophecy of Joel which was applicable to the events now transpiring, but he quotes that part also which pertains to the calamities coming on the Jewish nation, and to the final judgment (Joe 2:28-32). I understand Ac 2:19 to apply directly to the overthrow of Judea and Jerusalem.
2:19 And I will show prodigies in heaven above, and signs on earth beneath - Great revelations of grace are usually attended with great judgments on those who reject it. In heaven - Treated of, Ac 2:20. On earth - Described in this verse . Such signs were those mentioned, Ac 2:22, before the passion of Christ; which are so mentioned as to include also those at the very time of the passion and resurrection, at the destruction of Jerusalem, and at the end of the world. Terrible indeed were those prodigies in particular which preceded the destruction of Jerusalem: such as the flaming sword hanging over the city, and the fiery comet pointing down upon it for a year; the light that shone upon the temple and the altar in the night, as if it had been noon - day; the opening of the great and heavy gate of the temple without hands; the voice heard from the most holy place, Let us depart hence; the admonition of Jesus the son of Ananus, crying for seven years together, Wo, wo, wo; the vision of contending armies in the air, and of entrenchments thrown up against a city there represented; the terrible thunders and lightnings, and dreadful earthquakes, which every one considered as portending some great evil: all which, through the singular providence of God, are particularly recorded by Josephus. Blood - War and slaughter. Fire - Burnings of houses and towns, involving all in clouds of smoke.
2:14-21 Peter's sermon shows that he was thoroughly recovered from his fall, and thoroughly restored to the Divine favour; for he who had denied Christ, now boldly confessed him. His account of the miraculous pouring forth of the Spirit, was designed to awaken the hearers to embrace the faith of Christ, and to join themselves to his church. It was the fulfilling the Scripture, and the fruit of Christ's resurrection and ascension, and proof of both. Though Peter was filled with the Holy Ghost, and spake with tongues as the Spirit gave him utterance, yet he did not think to set aside the Scriptures. Christ's scholars never learn above their Bible; and the Spirit is given, not to do away the Scriptures, but to enable us to understand, approve, and obey them. Assuredly none will escape the condemnation of the great day, except those who call upon the name of the Lord, in and through his Son Jesus Christ, as the Saviour of sinners, and the Judge of all mankind.
