What does the Bible say about encouraging one another in the gospel?

In Romans 15, the Apostle Paul writes to the believers about the significance of encouraging one another in the gospel. He asserts that both the saved and the lost need the gospel, underscoring that preaching Christ is paramount for all. Encouragement comes from recognizing God's work in and upon us, fostering a community where believers can help one another grow in grace and knowledge. Paul insists that we should never cease in our encouragement, reminding fellow believers of the grace of God that has transformed their lives.
