What does Acts 18 teach us about preaching the gospel?

In Acts 18, Paul exemplifies the vital role of preaching the gospel in the advancement of God's Kingdom. He routinely reasons in the synagogues every Sabbath, persuading both Jews and Greeks about the truth of Jesus as the Christ. This action underlines the necessity of proclaiming the gospel message openly and scripturally, as faith comes by hearing (Romans 10:17). Furthermore, Paul's reliance on Scripture reinforces the belief that God's Word is the primary means through which He conveys truth and brings about regeneration in the hearts of the elect. As believers, we are called to follow this pattern, sharing the good news with others and trusting the Holy Spirit to make our efforts effectual.
