In Acts 16:6–15, we find the Lord sovereignly directing, working through, and adding to His people. Paul and his missionary team are guided by God to a new mission field, while simultaneously preparing hearts to receive the good news of the gospel. The passage presents “A Call to the Unconverted,” unfolding in two key moments which we will look at under their headings given in the English Standard Version of Scripture: 1. The Macedonian Call, and 2. The Conversion of Lydia.
