And suddenly there came a sound from heaven,.... Which is expressive of the original of the gifts and graces of the Spirit of God, which come from above, from heaven, from the Father of lights; and of the freeness of them, being unmerited; and so come suddenly, at an unawares, being unthought of, undesired, and unexpected, and so certainly undeserved; and may be a symbol of the sound of the Gospel, which from hence was to go forth into all the earth; and may likewise express the rise of that, and the freeness of the grace of God in it, and its sudden spread throughout the world:as of a rushing mighty wind; it was not a wind, but like one; and the noise it made, was like the rushing noise of a strong and boisterous wind, that carries all before it: the Spirit of God is sometimes compared to the wind, because of the freeness of his operations; as that blows where it listeth, so he works when and where, and on whom he pleases; and also because of the power and efficacy of his grace, which is mighty and irresistible, and works with great energy upon the minds of men; and as the wind is secret and invisible, so the operations of the Spirit are in a manner secret and imperceptible unto men: this may likewise be applied to the Gospel, when it comes with the Holy Ghost, and with power; it makes its way into the heart, and throws down the strong holds of sin and Satan; there it works effectually, though secretly, and is the power of God to salvation:and it filled all the house where they were sitting; which was the temple, or the upper room or chamber in it, where they were assembled; so in the Ethiopic confession of faith it is said,"the Holy Ghost descended upon the apostles, in the upper room of Zion;''this may be a symbol of the Gospel filling the whole world.
