What does the Bible say about salvation through the gospel?

Salvation is firmly rooted in the proclamation of the gospel as articulated in Romans 1:16, where Paul states, 'I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes.' This essential doctrine affirms that God has ordained the preaching of His Word as the means by which He brings about salvation. This is not merely the impartation of information, but a divine channel through which the Holy Spirit works to convert the hearts of the elect. The significance of this understanding lies in recognizing that God saves His people through means, particularly the faithful proclamation of the gospel, rather than through our efforts or understanding alone.
