Acts 4:5-12 features a boldness characterized by the Holy Spirit, which shows up just in time of need. The passage recalls the words of Jesus in Luke 12:11-12: “When they bring you before the synagogues, the rulers and the authorities, do not worry about how you are to defend yourselves or what you are to say, for the Holy Spirit will teach you that very hour what you ought to say.” Both passages foresee how Jesus’ followers will respond. For example, Peter is filled with the Holy Spirit in Acts 4:8 and answers in a way that Acts 4:13 calls “boldness”.
