What does the Bible say about calling on Jesus for salvation?

According to Romans 10:11-14, calling on the name of the Lord for salvation follows a genuine belief in Jesus Christ. The passage emphasizes that 'whosoever shall call upon the name of the Lord shall be saved,' highlighting the necessity of faith as a precursor to calling on Him. In essence, a person must first be given spiritual life to believe, and then they can sincerely call out for salvation. This indicates the importance of believing in the gospel message delivered by preachers sent by God, as faith cannot arise without hearing the truth.
