Acts forms an indispensable link between the accounts of Jesus' life (Gospels), their preaching in Acts (Kerygma) and their interpretations and applications in the New Testament letters. The early church developed and circulated two collections of NT writings: (1) the Gospels (four) and (2) the Apostle (Paul's letters). However, with the rise of the Christological heresies of the second century, the value of Acts became obvious. Acts reveals the content and purpose of Apostolic preaching (the Kerygma), as well as the amazing results of the gopel message.
“‘Jerusalem … Judea … Samaria … the remotest part of the earth’ This is a geographical outline of Acts: Jerusalem, chapters 1–7; Judea and Samaria, chapters 8–12; ends of the earth (i.e. Rome), chapters 13–28. This outline may denote the author’s literary structure and purpose. Christianity is not a sect of Judaism, but a worldwide movement of the one true God fulfilling His OT promises to restore rebellious mankind to fellowship with Himself (cf. Gen. 12:3; Exod. 19:5; Isa. 2:2–4; 56:7; Luke 19:46).” (Page 13)
“It was not that they kept part of the money, but that they lied to make themselves look spiritual. Notice that even a kind, generous act, which is done with a bad motive, is a sin. Notice that the Holy Spirit mentioned in v. 3 here is called God.” (Page 78)
“The third principle is to read the Bible in different translations in order to grasp the widest possible range of meaning (semantic field) that biblical words or phrases may have.” (Page iv)
“Sin begins in the thought life. The rabbis say that the mind is like a plowed garden ready for seed. What we allow in through our eyes and ears takes root. If we dwell on it, these thoughts become actions. This is why the NT asserts that we should ‘gird up the loins of our minds’ (cf. 1 Pet. 1:13) or ‘renew your mind’ (cf. Rom 12:2; Eph. 4:23).” (Page 115)
“But the gospel revolutionized and extended the OT concepts. The world-wide mandate (cf. Matt. 28:18–20; Acts 1:8) told believers to go into all the world, not wait for the world to come to them. Jerusalem of the NT is a metaphor for heaven (cf. Rev. 21:2), not a city in Palestine.” (Page 13)
