New Defender's Study Bible Notes
4:31 filled with the Holy Ghost. This was at least the second time that these early Christians in the Jerusalem church were filled with the Holy Spirit (note Acts 2:4). The “filling” of the Holy Spirit is not a once-for-all experience, but an oft-repeated experience, to be attained through earnest prayer and desire to honor God. Its manifestation is not usually that of supernatural speaking in other languages, as at Pentecost, but rather that of “speaking the word of God with boldness,” as on this occasion, and that of a joyful and godly Christian life (see Ephesians 5:18-20).
