How do we know grace is sufficient for sinners?

Grace is a central theme in the New Testament, often depicted as the unmerited favor of God. Ephesians 1:7 states, 'In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace.' This verse encapsulates the essence of grace as being rich and overflowing, providing a means of redemption for all sinners. The true understanding of grace brings comfort, especially for those burdened by guilt or sin. As seen in the story of the woman caught in adultery, Jesus offered grace, saying, 'Neither do I condemn thee; go, and sin no more' (John 8:11). This not only shows His mercy but also His authority to forgive sins.
