What does the Bible say about the progress of the Gospel?

The Bible indicates that the Gospel's progress is a divine plan, symbolized by Jesus as the 'Sun of truth and righteousness' (Psalm 19:6). While the initial spread of the Gospel was met with great reception, the passage of time has shown that it has not been embraced universally. The Apostle Paul highlights this in Romans 1:20, emphasizing that despite the clear revelation of God through creation, many remain unresponsive due to sin's influence on the human heart. The ongoing work of the Gospel is a testament to God's sovereignty, wisdom, and power, as He allows obstacles and opposition to reveal the sinfulness of humanity while still accomplishing His purposes.
