How does preaching the gospel save people?

Preaching the gospel is an instrumental means through which God conveys His saving grace to His people. Romans 10:17 states that 'faith comes by hearing, and hearing by the word of God,' highlighting that the act of preaching is essential for people to hear the gospel message and respond in faith. Through the preaching of the word, individuals are made aware of both their need for salvation and the sufficiency of Christ's sacrifice. This means that God's work of calling, illuminating, and saving individuals is closely tied to the faithful proclamation of the gospel.
