How do we know that God's grace and mercy are true?

The faithfulness of God's grace and mercy is rooted in His nature, which is revealed throughout Scripture. In Romans 9:15, Paul states, 'For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.' This declaration underscores the sovereign right of God to extend mercy according to His divine will, affirming that it is not based on human merit but on God's purpose and grace. Throughout the Bible, we see numerous instances where God provides mercy to those who are undeserving, emphasizing His nature as a loving and merciful Savior.

Additionally, the gospel is fundamentally built on the premise of grace. It teaches that salvation is a gift from God, not something that can be earned through works. Ephesians 2:8-9 affirms this by stating, 'For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast.' This truth reassures believers of God's unwavering commitment to mercy, directing us to depend on His grace rather than our own abilities.
