The conviction of sin that followed Peter's Spirit-filled preaching (2:37) was not momentary panic but a continuing uneasiness among those who had not yet received the word. The many wonders and miraculous signs done by God through the apostles served only to intensify this conviction. Whether the "signs and wonders" element be taken as normative for today (Wimber 1986:21) or as simply the authentication of a fresh stage of revelation (Stott 1974:13), clearly Luke is certain that the church's presence will have an impact on society.
