Why is longing for the kingdom of God important for Christians?

The desire for the kingdom of God signifies a shift away from worldly attachments and the fleeting nature of earthly life. Believers, who have been made new in Christ, experience a deep, abiding longing for the city that has foundations, whose builder and maker is God. The scriptures articulate this longing as a characteristic of those who have been truly awakened to the realities of eternity. This perspective enables Christians to seek after the things above rather than being mired in temporal concerns.
