This book unites the Gospels to the Epistles. It contains many particulars concerning the apostles Peter and Paul, and of the Christian church from the ascension of our Saviour to the arrival of St. Paul at Rome, a space of about thirty years. St. Luke was the writer of this book; he was present at many of the events he relates, and attended Paul to Rome. But the narrative does not afford a complete history of the church during the time to which it refers, nor even of St. Paul's life. The object of the book has been considered to be, 1. To relate in what manner the gifts of the Holy Spirit were communicated on the day of Pentecost, and the miracles performed by the apostles, to confirm the truth of Christianity, as showing that Christ's declarations were really fulfilled. 2. To prove the claim of the Gentiles to be admitted into the church of Christ. This is shown by much of the contents of the book. A large portion of the Acts is occupied by the discourses or sermons of various persons, the language and manner of which differ, and all of which will be found according to the persons by whom they were delivered, and the occasions on which they were spoken. It seems that most of these discourses are only the substance of what was actually delivered. They relate nevertheless fully to Jesus as the Christ, the anointed Messiah.
Verses 1-5 Our Lord told the disciples the work they were to do. The apostles met together at Jerusalem; Christ having ordered them not to depart thence, but to wait for the pouring out of the Holy Spirit. This would be a baptism by the Holy Ghost, giving them power to work miracles, and enlightening and sanctifying their souls. This confirms the Divine promise, and encourages us to depend upon it, that we have heard it from Christ; for in Him all the promises of God are yea and amen.
Verses 6-11 They were earnest in asking about that which their Master never had directed or encouraged them to seek. Our Lord knew that his ascension and the teaching of the Holy Spirit would soon end these expectations, and therefore only gave them a rebuke; but it is a caution to his church in all ages, to take heed of a desire of forbidden knowledge. He had given his disciples instructions for the discharge of their duty, both before his death and since his resurrection, and this knowledge is enough for a Christian. It is enough that He has engaged to give believers strength equal to their trials and services; that under the influence of the Holy Spirit they may, in one way or other, be witnesses for Christ on earth, while in heaven he manages their concerns with perfect wisdom, truth, and love. When we stand gazing and trifling, the thoughts of our Master's second coming should quicken and awaken us: when we stand gazing and trembling, they should comfort and encourage us. May our expectation of it be stedfast and joyful, giving diligence to be found of him blameless.
Verses 12-14 God can find hiding-places for his people. They made supplication. All God's people are praying people. It was now a time of trouble and danger with the disciples of Christ; but if any is afflicted, let him pray; that will silence cares and fears. They had now a great work to do, and before they entered upon it, they were earnest in prayer to God for his presence. They were waiting for the descent of the Spirit, and abounded in prayer. Those are in the best frame to receive spiritual blessings, who are in a praying frame. Christ had promised shortly to send the Holy Ghost; that promise was not to do away prayer, but to quicken and encourage it. A little company united in love, exemplary in their conduct, fervent in prayer, and wisely zealous to promote the cause of Christ, are likely to increase rapidly.
Verses 15-26 The great thing the apostles were to attest to the world, was, Christ's resurrection; for that was the great proof of his being the Messiah, and the foundation of our hope in him. The apostles were ordained, not to wordly dignity and dominion, but to preach Christ, and the power of his resurrection. An appeal was made to God; "Thou, Lord, who knowest the hearts of all men," which we do not; and better than they know their own. It is fit that God should choose his own servants; and so far as he, by the disposals of his providence, or the gifts of his Spirit, shows whom he was chosen, or what he has chosen for us, we ought to fall in with his will. Let us own his hand in the determining everything which befalls us, especially in those by which any trust may be committed to us.
