Why is the concept of being 'dead in sin' important for Christians?

The doctrine of total depravity teaches that humanity is inherently sinful and unable to save ourselves (Romans 3:23). By acknowledging that we are 'dead in sin' (Ephesians 2:1), Christians grasp the dire state of lostness that necessitates divine intervention. Ezekiel's vision of the dry bones epitomizes this condition; without God's 'I will' and the breath of His Spirit, there is no hope of life. This realization fosters humility and gratitude, reinforcing that salvation is entirely a work of grace, as we contribute nothing to our redemption but sin that necessitates it. Recognizing our deadness leads us to cherish the gift of grace and the power of Christ's resurrection.
