How do preaching and belief relate in salvation?

The message of salvation is delivered through preaching, as emphasized in Romans 10, which states that faith comes by hearing, and hearing by the word of God. The preacher serves as a vessel through which the Spirit works to call the elect to believe in Christ. This reinforcement of the gospel through preaching affirms that salvation is not of the will of man but is entirely operated according to God’s sovereign purpose. Belief is a response to the effective call of God through the gospel, which is the means of grace for the elect.
