14 These all with one accord continued stedfastly in prayer, with the women, and Mary the mother of Jesus, and with his brethren.

15 And in these days Peter stood up in the midst of the brethren, and said (and there was a multitude of persons [gathered] together, about a hundred and twenty), 16 Brethren, it was needful that the Scripture should be fulfilled, which the Holy Spirit spake before by the mouth of David concerning Judas, who was guide to them that took Jesus.

Commentary on Acts 1:12-14

(Read Acts 1:12-14)

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.

Commentary on Acts 1:15-26

(Read Acts 1:15-26)

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.
