How do we know grace is true according to the Bible?

The reality of grace is fundamentally rooted in the nature of God as revealed in Scripture. In 1 Corinthians, Paul opens his letter by acknowledging the grace that believers have received, which is a gift from God that does not depend on human merit. This aligns with biblical teachings found in passages such as Ephesians 2:8-9, which states that salvation is by grace through faith, not of works, lest anyone should boast. Moreover, God's sovereignty in dispensing grace, as illustrated in Romans 9:15-16, demonstrates that He extends His mercy to whom He chooses. This grace is not a mere abstract concept but is tangibly demonstrated in the life, death, and resurrection of Jesus Christ, who provided a means for sinners to be reconciled to God. Therefore, grace is true and trustworthy, founded on God's faithfulness and unchanging character.
