Faith come by hearing....!
So then faith comes by hearing, and hearing by the word of God.
Romans 10:16-18
Can’t have regeneration unless you first hear.
The gospel saves us. Rom. 1:16 For I am not ashamed of the gospel of Christ,[a] for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek. 17 For in it the righteousness of God is revealed from faith to faith; as it is written, “The just shall live by faith.”[b]
And you can't hear unless God specifically opens your ears to do so. He who has ears let him hear. Yes, God uses the preaching of the Gospel to implement his preordained decisions regarding salvation. It is his chosen method. This way a single act works to both sanctify the evangelist and justify the sinner.
