20 For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, 21 who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself. (Philippians 3:20–21, NKJV)
Citizenship identifies a person as a legal member of a nation. It qualifies that person to participate in the rights and privileges of that nation. In contrast to “the enemies of the cross of Christ” (“whose end is destruction, whose god is their belly, and whose glory is in their shame—who set their minds on earthly things,” Phil. 3:18-19), Christians are qualified “to be partakers of the inheritance of the saints in the light” (Col. 1:12). By faith, we eagerly wait for the Savior’s return, living in hope of the glorious resurrection in anticipation of our heavenly estate (Heb. 11:14-16). Christ will subdue (subjugate, defeat) death in the resurrection (1 Cor. 15:24-28). Kingdom citizens will be delivered up to God the Father to dwell forever in the eternal city of God (1 Cor. 15:23-24; Rev. 21:22-27). These great assurances compel the wise and faithful of heart to answer the gospel call to be saved, to become citizens of heaven (Acts 2:37-41; Col. 1:13). Christians set their minds on things above, not on earthly things (Col. 3:2). Let us live for the glory of heaven daily, not for things that end in destruction.
