Jesus did not come to reestablish His own throne; God is King - that was never the issue. His mission was to restore us, His fallen creation, His wayward sons and daughters. Through His death, burial, resurrection, and ascension, He has made it possible for us not only to be reconciled with the Father but also to be rejoined to His family and once again given a renewed purpose to fulfill humanity's original design.
The invitation of the gospel is the invitation to come home. It is the invitation to lay down the burden of self-rule and once again joyfully live under the benevolent reign of the true King. Through Christ, we are welcomed back into God's Kingdom, restored to fellowship with our Father, and called to serve as His royal priesthood, faithfully representing His will upon the earth until the day His Kingdom is fully revealed.
