Why should we rely on God's grace?

Relying on God's grace is essential for believers because it shifts our focus from self-effort to the sufficiency of Christ's sacrifice. Hebrews 13:9 states that it is good for the heart to be established with grace, suggesting that grounding our faith in grace strengthens our confidence and assurance in God's promises. Additionally, 2 Timothy 1:9 emphasizes that God has saved us and called us according to His own purpose and grace. This assurance empowers us to live boldly, knowing that our standing with God is not based on our fluctuating performance but on His eternal faithfulness and love.
