Acts 12:24 - Albert Barnes' Notes on the Bible

But the word of God grew ... - Great success attended it. The persecutions had now ceased; and notwithstanding all the attempts which had been made to crush it, stir the church increased and flourished. The liberation of Peter and the death of Herod would contribute to extend it. It was a new evidence of divine interposition in behalf of the church; it would augment the zeal of Christians; it would. humble their enemies, and would fill those with fear who had attempted to oppose and crush the church of God.
