What does the Bible say about the Apostle Paul's mission to preach the gospel?

In Romans 15, the Apostle Paul expresses his passionate desire to preach the gospel in areas where Christ has not yet been named, illustrating his commitment to fulfilling the Great Commission. As part of his mission, he aimed to open new routes and cross borders to reach Gentile territories. He wasn't just focused on building upon existing foundations but rather sought to bring the good news of Christ to the lost, in obedience to the Holy Spirit's leading. This shows how central evangelism is to the life of a believer and the church, urging us all to engage in spreading the gospel.
