What does it mean that the gospel covers the earth?

The proclamation of the gospel is a central aspect of God's sovereign plan. The Scriptures affirm that God's grace is expansive and reaches every corner of the earth, as seen in Romans 10:18 which states, 'But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.' This fulfillment of God's promise emphasizes that His gospel will not be hindered by any power. It is through the preaching of the gospel that God calls His elect from every tribe and nation, showcasing His sovereignty and grace in gathering His people across the globe.
