How does God convey the Gospel through earthen vessels?

In His sovereign design, God has chosen to use earthen vessels—imperfect, human instruments—to convey the perfect message of the Gospel. This is illustrated in the ministry of the Apostle Paul, who recognizes himself as a vessel of mercy. The use of earthen vessels underscores that the effectiveness of the message is not due to the vessel's excellence but to the power of God that accompanies it. Whether through preaching or personal testimony, God employs frail humans to communicate His truths, ensuring that the glory remains with Him, as no flesh can boast in His presence. This underscores the need for reliance on God's strength, opening a path for His transformative power to work through our weaknesses.
