How do we know God's grace is sufficient for believers?

The sufficiency of God's grace for believers is foundational in Reformed theology, rooted in the work of Jesus Christ. 2 Corinthians 12:9 states, 'My grace is sufficient for you, for my power is made perfect in weakness.' This assurance indicates that God's grace is not only adequate but also abundant for those who trust in Him. It reflects the heart of the gospel, where grace is freely given to sinners who cannot earn salvation through their works. As seen in the story of redemption, grace flows from God's love, fulfilling His promises to His people from eternity. It underscores the fact that through Christ’s perfect life and atoning death, believers are declared righteous, receiving grace as a gift rather than a wage.
