Why is repentance significant in calling upon God?

Repentance is a key aspect of calling upon God, as it signifies genuine acknowledgment of our sinful condition and the need for divine mercy. Scripture indicates that the 'goodness of God leads you to repentance' (Romans 2:4). Therefore, true calling involves not just asking for salvation but also turning away from sin and towards God, believing that He alone can save us through Christ's righteousness. The process of repentance goes hand-in-hand with faith, demonstrating the believer's willingness to embrace God's grace and forgiveness.
