How do we know that God saves those who call upon Him?

The certainty of God's saving power is clearly articulated in Romans 10:13, which assures us that 'whosoever shall call upon the name of the Lord shall be saved.' This promise is rooted in God’s character and His covenantal faithfulness. Just as David experienced God's saving grace in his life, it exemplifies the broader truth that God is always willing to redeem those who come to Him in sincere faith. Throughout the Bible, God's past acts of salvation serve as a testimony to His ongoing commitment to save His people. This is emphasized throughout the biblical narrative, from the deliverance of Israel from Egypt to the atoning work of Christ on the cross.
