What happens when we say yes to going? That question sits at the heart of Acts 15 through 18, where we follow Paul and his companions through one of the most turbulent and transformative stretches of missionary work in the New Testament. This is not a tidy story of smooth success. It is a raw, honest account of doctrinal conflict, broken partnerships, divine detours, imprisonment, beatings, and discouragement. And yet, threaded through every hardship is a pattern we cannot ignore: opposition consistently gives way to advancement.
