Why is the doctrine of Christ's second coming important for Christians?

Christ's second coming is a cornerstone of Christian hope and doctrine because it confirms that God is sovereign over history and will bring about perfect justice and restoration. Believers are promised that Christ will return in power and glory to judge the living and the dead. This doctrine provides comfort and encourages perseverance in faith, as it signifies that the struggles and tribulations faced in this life are temporary and culminate in the eternal presence of God, where He makes all things new.
