How can we say we are perfect when we still sin?

Although Christians still struggle with sin, their position before God is one of perfection, based on Christ's sacrifice. Hebrews 10:14 states that by the one offering of Christ, we have been perfected forever. This perfection is attributed to Christ's righteousness rather than our failed attempts at righteousness. Therefore, while we recognize our sinful nature, we also embrace our identity as those completely redeemed and made righteous through faith in Jesus—an essential tenet of sovereign grace theology.
