The Kingdom of God
In Christ’s eschatological glory he overturns what was broken and advances the world order to its God-appointed end. Christ delivers a decisive death blow to the old age—that realm in which Satan rules, sin dominates, and death reigns—and Christ constitutes the new age, the new creation reality, also known as “the kingdom of God.” In his resurrection, the new age has begun.
