How do we know that God sends ministers to preach the gospel?

In Romans 10, the apostle Paul asserts the necessity of preaching, stating, 'How shall they preach except they be sent?' This indicates that God has a deliberate plan to send His ministers to share the gospel, demonstrating His sovereign grace. Additionally, in 2 Thessalonians 2:13, Paul reminds believers that God has chosen them for salvation, further confirming that the preaching of the truth is part of God's eternal purpose. This connection between divine calling and gospel proclamation underscores the importance of acknowledging those sent by God in ministry.
