This teaching from Spirit University explains the biblical difference between the indwelling of the Holy Spirit, received at salvation (John 14:16–17; Romans 8:9), and being filled with the Spirit, a repeated empowerment believers must seek (Ephesians 5:18; Acts 4:31). Drawing from Acts 2, Dr. Fred K. Price describes Pentecost as the miraculous moment when diverse nations heard God’s message in their own languages (Acts 2:6–8). He emphasizes that this filling furnishes believers with supernatural ability beyond the flesh (Galatians 5:16). The message concludes with a warning not to mock the Spirit’s work, likening His influence to “new wine” (Acts 2:13; Ephesians 5:18).
