What does the Bible say about furthering the gospel?

In Philippians 1:12, Paul expresses that the difficulties he faces are ultimately for the furtherance of the gospel. This teaching extends throughout Scripture, such as in Romans 8:28, which affirms that all events in a believer's life serve God's sovereign purpose, including the spread of the gospel. Persecutions, trials, and afflictions are often tools used by God to advance His message and draw people to Himself. This ongoing process reflects God's overarching objective to reveal His glory through the salvation of His people.
