The promise of the baptism of the Spirit is fulfilled at Pentecost, one of the seven feasts given to the Hebrews. The believer's ability to walk in the power of God is further examined, and we look at the difference between baptism of the Spirit and being filled with the Spirit. The tongues used in Acts 2 are explained, and we find as the text ends, that God's power is always met with resistance from the enemy.
