Greek Key Terms:
Context: Acts 2:14-37 records Peter's Pentecost sermon. He interprets the Spirit's outpouring as fulfillment of Joel's prophecy (vv. 16-21), proclaims Jesus' death, resurrection, and exaltation (vv. 22-36), and convicts his hearers: "You crucified" the Messiah (vv. 23, 36). The crowd responds, "Brothers, what shall we do?" (v. 37). Verses 38-41 give Peter's answer and the result.
Connections:
Christological Connection: The contrast between Sinai and Pentecost is the heart of the typology. Sinai (Exodus 19-32): God gave the Law on stone tablets (Exodus 31:18). Israel violated the covenant by worshiping the golden calf (Exodus 32). Moses commanded judgment: "There fell of the people that day about three thousand men" (Exodus 32:28). Pentecost (Acts 2): God poured out the Spirit, writing the Law on hearts (Hebrews 10:16, fulfilling Jeremiah 31:33). Peter preached Christ crucified and risen. The people repented and believed: "There were added that day about three thousand souls" (Acts 2:41). The reversal is exact: Sinai = Law on stone, covenant broken, 3,000 died. Pentecost = Law on hearts, covenant fulfilled, 3,000 saved. Paul's statement applies: "The letter kills, but the Spirit gives life" (2 Corinthians 3:6). The Law revealed sin and condemned; the Spirit transforms and saves. Pentecost is the firstfruits of the gospel harvest—3,000 Jews from every nation, the beginning of the multinational church. The Feast of Weeks is fulfilled: the wheat harvest gathered by the Spirit.
Application: Repent and believe. Peter's call is urgent: "Repent and be baptized...for the forgiveness of your sins" (v. 38). Have you repented—turned from sin to Christ? Repentance is not mere regret but a radical reorientation of life. Receive the Spirit. The promise is for all believers: "You will receive the gift of the Holy Spirit" (v. 38). If you have trusted Christ, you have the Spirit (Romans 8:9). The Spirit is not earned but received as a gift. Identify with Christ. Baptism publicly identifies you with Christ's death, burial, and resurrection (Romans 6:3-4). Have you been baptized? Baptism doesn't save you, but it declares your faith. Separate from the world. "Save yourselves from this crooked generation" (v. 40). The church is a called-out people, distinct from the world. Are you living as a citizen of heaven (Philippians 3:20), or conforming to this age? Pentecost teaches that the Spirit creates a new people—repentant, Spirit-filled, Christ-identified, and world-distinct. Be part of the harvest.
Connection Method(s): Typology (Direct, Backward-Looking), Contrast — The 3,000 saved at Pentecost exactly reverses Sinai's 3,000 dead, demonstrating that the Spirit gives life where the letter killed, fulfilling the Feast of Weeks' harvest typology.
