What does the Bible say about the role of preaching in salvation?

Ephesians 4 emphasizes that Christ ascended on high and gave gifts to men, appointing preachers to proclaim the good news. This preaching is not merely an act of human wisdom; rather, it is through this foolishness that God effectively calls His elect. As stated in 1 Corinthians 1, God uses the weak and despised things of this world to confound the wise, demonstrating that salvation is entirely His work and for His glory. Through preaching, believers are not only saved but are also educated and nurtured in their faith throughout their entire lives.
