Acts 12:20-25 Compare Daniel 4:28-37 Application? (See Daniel 4:1-27 on your own for the backstory to this text. Note how long it was between the dream and the fulfillment in verse 29. What does that suggest about the patience of God?). Now see Jeremiah 17:9. What does that suggest about humanity's fundamental problem? Compare also CS Lewis: A proud man is always looking down on things and people; and, of course, as long as you’re looking down, you can’t see something that’s above you.
What does humility have to do with all this? Consider the prayer of Cardinal Merry de Val: Litany of Humility. How might a person's life change as a result of frequently praying that litany?
13:1 Note the comment about Manaen. See Matthew 14:1-11. How does one turn out to be a Herod and another to be a Manaen? Read my essay titled, Child or Tool here: http://thecontemplativecatholicconvert.blogspot.com/2012/04/child-or-tool.html Might that speak to the question?
13:2-5 This 'sending' is clearly not reserved only for apostles, bishops, priests and religious. They do not work where we work, shop where we shop, live where we live, study where we study. The gospel would never cover the world if Jesus left it only to the clergy. Consider the role of the Church (comprised of clergy and laity) cited in the Catechism paragraphs 849-852 (below) as well as the excerpts from Pope Benedict, Pope Paul the VI and Thomas a Kempis (also below). (BOLDED highlights are for my emphasis).
849 The missionary mandate. "Having been divinely sent to the nations that she might be 'the universal sacrament of salvation,' the Church, in obedience to the command of her founder and because it is demanded by her own essential universality, strives to preach the Gospel to all men":339 "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and Lo, I am with you always, until the close of the age."340
850 The origin and purpose of mission. The Lord's missionary mandate is ultimately grounded in the eternal love of the Most Holy Trinity: "The Church on earth is by her nature missionary since, according to the plan of the Father, she has as her origin the mission of the Son and the Holy Spirit."341 The ultimate purpose of mission is none other than to make men share in the communion between the Father and the Son in their Spirit of love.342
851 Missionary motivation. It is from God's love for all men that the Church in every age receives both the obligation and the vigor of her missionary dynamism, "for the love of Christ urges us on."343 Indeed, God "desires all men to be saved and to come to the knowledge of the truth";344 that is, God wills the salvation of everyone through the knowledge of the truth. Salvation is found in the truth. . . . . Because she believes in God's universal plan of salvation, the Church must be missionary.
852 Missionary paths. The Holy Spirit is the protagonist, "the principal agent of the whole of the Church's mission."345 It is he who leads the Church on her missionary paths. "This mission continues and, in the course of history, unfolds the mission of Christ, who was sent to evangelize the poor; so the Church, urged on by the Spirit of Christ, must walk the road Christ himself walked, a way of poverty and obedience, of service and self-sacrifice even to death, a death from which he emerged victorious by his resurrection."346So it is that "the blood of martyrs is the seed of Christians."347

Question for further reflection: How do you see your role in the missionary mandate of our Lord Jesus Christ? What talents, time and treasure are you dedicating to the building up of the Kingdom of God? Why not consider asking the Holy Spirit to reveal to you ways in which you might increase your commitment to God's work on earth?
