Every person faces a choice between two ways: the narrow way that leads to life or the broad way that leads to destruction, heavenly treasures or worldly treasures, the kingdoms of this world that can be shaken or the Kingdom that cannot be moved. Human empires, governments, and institutions are made by finite, sinful men, so they are corrupt and temporary, and God shakes them down. Babylon, Persia, Greece, Rome, and every empire since have collapsed, and the same fate awaits any global empire Satan raises up. The most urgent question for anyone is therefore not who governs the nations but whether he personally belongs to the eternal Kingdom. There is a way of escape from the collapsing kingdoms of men, and there is only one way of entering the Kingdom of God. Citizenship is in heaven, awaiting the return of the Savior, Jesus Christ, who will transform lowly bodies to be like His glorious body (Philippians 3:18-21). Those who belong to the kingdoms of men will be destroyed with them. Hebrews 12:25-29 says believers are receiving a Kingdom that cannot be shaken, so they must not refuse Christ, who speaks from heaven, but serve God with reverence and godly fear. That Kingdom rests on God's unshakable Word and law, and believing that Word builds faith. Because everything seen will dissolve, believers should set their treasure in heaven, live holy lives, and be strong, trusting that God is with them.

Only those who are born again will see and enter the Kingdom of God (John 3:3, 5). Spiritual birth is necessary because people are spiritually dead in trespasses and sins until God makes them alive (Ephesians 2:1-6), and the dead cannot direct their steps or praise God truly. Jesus' word "see" (eidon) means to know, perceive, and understand, so without new birth a person cannot comprehend the things of God or be fitted for the Kingdom. Nicodemus, like others in John, misreads Jesus' spiritual imagery as physical and so misses the point. The Greek gennao combined with anothen indicates a second birth, not a conception, and regeneration likewise marks a new beginning. Converted Christians are pictured as functioning adults, not fetuses in a womb. The Kingdom is not only future but a present, spiritual reality that can be entered immediately when God's requirements are met. Jesus proclaimed that it was "at hand" (Mark 1:15), and it was present in His person and ministry ("among you," Luke 17:21). Entry has conditions: righteousness exceeding that of the Pharisees, doing the Father's will, and becoming converted like little children (Matthew 5:20; 7:21; 18:3). Those who are born again, called, and given the Holy Spirit are already conveyed into the Kingdom of the Son (Colossians 1:13), hold heavenly citizenship (Philippians 3:20), and serve as ambassadors for Christ. They need not wait for the resurrection at Christ's return to be counted part of the Kingdom, though it will not be manifest in fullness until then.

No one can enter the Kingdom of God unless he is born again, born of water and the Spirit (John 3:5). Water and Spirit form a hendiadys: one idea, with water intensifying Spirit as the cleansing, life-giving, thirst-quenching work of God's Holy Spirit and Word, not a reference to baptism. Entry is wholly God's gracious act. Man is spiritually dead and carnal, and flesh can only produce flesh, so no one can volunteer for entry or cause his own new birth (John 6:44; Romans 9:15-16). God closes the gap by calling, bringing repentance, granting forgiveness through Christ's blood, and imparting His Spirit. The new birth is the impartation of God's nature, the mind of Christ, and the beginning of a new spiritual man within the physical, not a change of bodily composition or a post-resurrection event. Every born-again person is instantly a child of God, a member of His Family, and a citizen of the Kingdom, addressed as a capable adult rather than a spiritual fetus. Baptism pictures the burial of the old man and does not cleanse. Two natures now war within the believer, who must choose to overcome the flesh and grow into the fullness of Christ. The fruit of the Spirit is evidence that one is already born of the Spirit and has entered the Kingdom.
