How do we know grace is truly amazing?

John 1:16 reminds us that 'of His fullness have all we received, and grace for grace.' The amazing nature of grace lies in its capacity to redeem us from our sin and restore us to a right relationship with God. The speaker points out that our shameful past and experiences of sin provide us with a richer understanding of God's grace, as it reveals the profound love and mercy He has towards sinners. Indeed, without sin, we wouldn't grasp the depth of grace and the need for a Savior, exemplified in Romans 5:20, where sin abounded, grace did much more abound.
