How do we know that God sends preachers to deliver His message?

The sending of preachers is rooted in God's sovereign plan. According to Romans 10:13-15, 'how shall they preach except they be sent?' This indicates that it is God who commissions and ordains His messengers. Throughout scripture, we see instances where God raises up individuals to deliver His message, fulfilling His purpose for the salvation of His elect. Therefore, it is by God's will that preachers are sent to those who have yet to hear the gospel, assuring that His word reaches the chosen.
