Pastor Brian focuses on Acts 9:32-43, where Peter heals Aeneas and raises Dorcas, leading to widespread faith. Brian emphasizes the power of small acts of obedience which can have significant community impact. He encourages the congregation to see their daily acts of kindness and obedience as part of God's plan to transform their city, likening it to the butterfly effect and the ripple of faith seen in biblical figures like Elijah and Elisha.
