How do we know God saves through preaching?

Scripture consistently attests to the notion that God employs preaching as the primary means of salvation for His people. In 1 Corinthians 1:21, we see that it pleased God to use the foolishness of preaching to save those who believe. This means that preaching is not just an afterthought or a supplementary activity but a divinely appointed method God uses to confront the wisdom of the world, proclaim the Gospel, and bring people to faith. The very essence of preaching as God’s means also emphasizes His sovereignty in salvation, ensuring that none will come to faith apart from hearing the Gospel proclaimed.
