What does it mean that Christ is both Savior and Judge?

Christ's dual role as Savior and Judge is a central theme in sovereign grace theology. Through His life, death, and resurrection, He offers salvation to those whom the Father has chosen, providing forgiveness for their sins and uniting them with Himself. However, the same Christ who extends grace is also the one who will judge those who reject Him. This is illustrated in the Exodus story where the waters that saved Israel drowned the Egyptians. The reality of salvation is not universal; rather, it is for God's elect, while judgment is reserved for those who turn away from His Word.
