The sermon centers on the healing of a man lame from birth in Acts 3:1–10, illustrating how the Holy Spirit empowers believers to witness and minister with compassion. It emphasizes that true spiritual transformation—miraculous in nature—occurs when individuals, though spiritually dead and unable to help themselves, are made alive in Christ through grace. The miracle is not merely physical but symbolic of the complete, instantaneous, and perfect salvation available to all who look to Jesus in faith. The healed man's immediate response—walking, leaping, and praising God—demonstrates the inevitable fruit of genuine conversion, compelling others to marvel and recognize the power of God at work. The passage calls believers to live with such visible transformation that their lives testify to the grace they have received, making their testimony undeniable and their witness compelling.
