On This Day: The Theology of Pentecostal Conviction and Proclamation

The Command for Repentance and Baptism: Peter explicitly instructs the assembly to "repent and be baptized." * Scope: Every individual must be baptized in the name of Jesus Christ. * Purpose: The primary objective of this act is the forgiveness of sins. * The Reward: Upon completion, the believer receives the "gift of the holy spirit."
The Universality of the Promise: The speaker emphasizes that this promise is not limited to those present but extends across time and geography: * It is for the listeners themselves. * It is for their children (multigenerational). * It is for "all who are far off." * It includes "everyone whom the lord our god calls to have."
The Exhortation for Separation: Peter continued to bear witness and exhort the crowd with many other words, specifically commanding them to "save yourselves from this crooked generation."

The Day of Pentecost: This event is celebrated worldwide in the Greco-Roman calendar. The speaker refers to this specific message as "On This Day."
The Scale of Growth: * On that single day, approximately $3,000$ souls were added to the number of believers after receiving the word and being baptized. * This is contrasted with the initial group in the upper room, which consisted of approximately $120$ individuals.
The Temporal Sequence of Events: * At $9:00\,\text{in the morning}$ , the Holy Spirit descended on the individuals in the upper room, who began speaking in tongues that matched the native languages of those gathered for the festivals. * At this time, those outside the original $120$ began to mock the spirits. * Only $3\,\text{hours}$ later, at approximately noon, the same crowd that mocked the spirit was "stabbed by the word."

Definition of "Cut to the Heart": When the author Luke wrote that the listeners were "cut to the heart," he was employing specific surgical language. * It does not imply a "soft cut" or a mild emotional response typical of a standard Sunday school message. * The term signifies being "stabbed," "pierced through," or "run through like a sword." * The Cutting Agent: The word of God itself acts as the blade. The speaker notes that one does not "intellectualize the wound" or argue with the blade; one simply reacts to the injury.
The Linguistic Nuance of "What Shall We Do?": * In the Greek context, this is not a philosophical or academic inquiry intended to help the listener understand a concept. * It is the language of panic and complicity. * It represents the sudden realization of being on the "wrong side" and having participated in the killing of the Messiah.

The Required Posture for Revelation: * The speaker argues that you cannot ask "What shall we do?" from a position of comfort. * The question is asked "on the floor in your tears" when a person reaches a true revelation of themselves in relation to Christ.
The Goal of the Sermon: * Peter’s sermon did not end with applause or admiration for his speaking ability. * It ended in desperation. * The speaker notes that Peter did not preach until the people "liked him"; he preached until they "saw themselves." * The intended response to the first post-ascension proclamation was not approval, but a desperate need for change.

Core Principles of the Church: The speaker identifies three specific principles that govern the church's operation: 1. Prayer 2. Presence 3. Proclamation
Scriptural Foundation (Colossians 1:28): * The speaker references this text to define the church’s mission: "Him we proclaim." * The process involves "warning everyone and teaching everyone with all wisdom." * The ultimate goal is "that they may be present to everyone in maturity in Christ."
Inspiration vs. Maturity: The speaker draws a sharp distinction between "inspirational preaching," which aims to make people feel good, and the biblical model of proclamation, which aims for maturity through conviction.
