Acts 2:2

And suddenly there came a sound from heaven, as of a rushing mighty wind, &c.--"The whole description is so picturesque and striking that it could only come from an eye-witness" [OLSHAUSEN]. The suddenness, strength, and diffusiveness of the sound strike with deepest awe the whole company, and thus complete their preparation for the heavenly gift. Wind was a familiar emblem of the Spirit (Eze 37:9; Joh 3:8; Joh 20:22). But this was not a rush of actual wind. It was only a sound "as of" it.

Between the promise of the Messiah (even the latest of those promises) and his coming many ages intervened; but between the promise of the Spirit and his coming there were but a few days; and during those days the apostles, though they had received orders to preach the gospel to every creature, and to begin at Jerusalem, yet lay perfectly wind-bound, incognito - concealed, and not offering to preach. But in this chapter the north wind and the south wind awake, and then they awake, and we have them in the pulpit presently. Here is, I. The descent of the Spirit upon the apostles, and those that were with them, on the day of pentecost (Act 2:1-4). II. The various speculations which this occasioned among the people that were now met in Jerusalem from all parts (Act 2:5-13) III. The sermon which Peter preached to them hereupon, wherein he shows that this pouring out of the Spirit was the accomplishment of an Old Testament promise (Act 2:14-21), that it was a confirmation of Christ's being the Messiah, which was already proved by his resurrection (Act 2:22-32), and that is was a fruit and evidence of his ascension into heaven (Act 2:33-36). IV. The good effect of this sermon in the conversion of many to the faith of Christ, and their addition to the church (Act 2:37-41). V. The eminent piety and charity of those primitive Christians, and the manifest tokens of God's presence with them, and power in them (Act 2:42-47).
