And everyone who has left houses or brothers or sisters or father or mother or wife or children or lands, for My name’s sake, shall receive a hundredfold, and inherit eternal life. (Matthew 19:29, NKJV)
Jesus had previously explained the kingdom of God is not entered by the power of money and human expectations, but by the power of God (Matthew 19:23-26). After assuring the apostles of their reward of service in the kingdom, Jesus went on to explain how kingdom entrance requires sacrifice and devotion by everyone who wants kingdom citizenship (19:29). One is not entitled to kingdom citizenship who does not enter it correctly. I cannot simply enter the kingdom by expecting citizenship. Everyone who wants to be in the kingdom of God must leave behind (forsake, yield up, let go) everything for the sake of Jesus Christ. That’s what Jesus said. Whether it is possessions or people, Christ demands first place in our hearts and lives or we will not be regenerated (born again, saved, and conveyed into the kingdom, cf. Luke 14:33, 26; Colossians 1:13-14). Many spiritual blessings accrue here and now to the disciple of Christ (Ephesians 1:3). And finally, the inheritance of eternal life is the faithful Christian’s reward (2 Timothy 4:8; 1 Peter 1:3-5). Blessings from heaven belong to all who submit to the will of Jesus (Acts 3:19). Every attempt to enter God’s kingdom without doing the will of God will fail (Matthew 7:21).
27 Then Peter answered and said to Him, “See, we have left all and followed You. Therefore what shall we have?” 28 So Jesus said to them, “Assuredly I say to you, that in the regeneration, when the Son of Man sits on the throne of His glory, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel.” (Matthew 19:27–28, NKJV)
The faithful apostles had left their professions and possessions to follow Jesus (Mark 1:16-20; Luke 5:11). Their subsequent work in the kingdom of God justified their sacrificial faith. Christ gave them authority to judge among the “twelve tribes of Israel” (i.e., the people of God, Romans 9:6-8; Galatians 6:16) by the gospel they proclaimed (Mark 16:15; 2 Thessalonians 2:15; Romans 2:16). Christ’s reign and their authority to judge coincide with “the regeneration,” a reference to the time of salvation which began in Acts 2 and continues until His return (Acts 2:29-41; 2 Corinthians 6:1-2; 5:17). Even as the Son of Man now reigns in glory, the apostles’ word is the standard of authority by which souls are regenerated (born again, John 3:3-5; 2 Corinthians 5:17-21). We take comfort and courage in knowing that when we sacrifice all to follow Jesus, He has prepared eternal glory with Him for us (Colossians 3:4).
3 Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.” 4 Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?” 5 Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.” (John 3:3–5, NKJV)
The new birth is a spiritual birth, not a physical one: “That which is born of the flesh is flesh, and that which his born of the Spirit is spirit” (John 3:6). There is one new birth, with two parts (water and the Spirit). To be “born again” one must be “born of water and the Spirit.” What is the “water” of the new birth? It is not the water of physical birth, but the water of spiritual birth. It is the “washing of water” that happens when sin is washed away by the blood of Christ. It is the cleansing that occurs in water baptism (read Acts 22:16; Romans 6:3; Acts 8:35-39). The Bible says, “baptism doth also now save us” (1 Peter 3:21, KJV). What is “the Spirit” of the new birth? It is the Spirit of God, whose seed (the word of the kingdom) is planted into the heart of the sinner (Matt. 13:19, 23; Ephesians 5:26; 1 Peter 1:22-23). The Spirit of God acts upon the heart by His word, producing faith, convicting the sinner, and persuading him to obey Jesus to be saved (Acts 2:37-38, 39-41). The new birth is “not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit” (Titus 3:5). Have you been born of water and the Spirit? Only then can you enter the kingdom of God (John 3:5).
