How do we know that repentance leads to salvation?

Repentance, as shown in the lives of the Israelites, is not merely a feeling of regret but a transformation that leads to a genuine turn towards God for salvation. In Romans 10:13, we see the promise that all who call upon the name of the Lord will be saved. This aligns with the understanding that faith is the evidence of salvation and that a genuine repentance will naturally express itself in a plea for mercy and forgiveness from God. The Israelites, after recognizing their need, cried out for help, demonstrating that true repentance produces a desire for reconciliation with God, ensuring salvation.
