Why is it important for Christians to understand they are completely cleansed?

For Christians, the understanding of being completely cleansed from sin is fundamental because it shapes our identity as children of God. It allows us to live without the burden of guilt and shame, as we can approach God with confidence, knowing that we have been entirely forgiven. This truth compels us towards gratitude and worship, as we recognize the depth of God's grace towards us. Moreover, acknowledging our complete cleansing ensures that we depend solely on Christ for our salvation and do not trust in our own righteousness, which remains like 'filthy rags' before God.
