What does the Bible say about calling upon the name of the Lord?

In Romans 10:13, the apostle Paul emphasizes the inclusiveness of God's offer of salvation, declaring that 'whosoever shall call upon the name of the Lord shall be saved.' This verse encapsulates the promise that anyone, regardless of their background, can receive salvation through calling on the Lord. However, it is crucial to understand that calling upon the Lord involves a heartfelt acknowledgment of Him as Savior and Lord, stemming from a renewed heart given by God. The context makes it clear that the call is a response to God's initial work of grace in the sinner's heart, whereby they come to believe and trust in Christ’s redemptive work.
