Acts 2:1–4 records the church’s beginning on God’s appointed day. Heaven descends with the sound of wind and the sign of fire; the Spirit baptizes believers into Christ and then fills them to speak in real languages, declaring the mighty works of God. In this message, you’ll see the difference between Spirit baptism (our once-for-all union with Christ) and Spirit filling (God’s ongoing power for daily witness), and you’ll be invited to wait on God, walk in unity, and speak for Jesus with clarity and courage.
