Jesus says to Nicodemus, "Unless one is born from above he cannot see the kingdom of God." (v. 3) Nicodemus responds --"How can a man be born when he is old?" Jesus answered, "Unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit." (vv. 5-6) In these words, Jesus made the conditions for entering the kingdom clear. The kingdom of God is not entered by anything we do, but through a transformation brought about by God. We do not enter the Spirit's realm through our own efforts. We enter the realm of God's Spirit through the water of Baptism and the Holy Spirit's efforts. Baptism is the washing of regeneration -- rebirth. Through it, the Spirit adopts us as his own, bringing us under his dominion. Jesus offered Nicodemus and us the key to understanding. What is "heavenly" has come to earth: "the Son of man" (v.13). In the Son, God has come to earth and opened his heart and will to us. Perishing in spiritual confusion and death, we have only to look to Jesus to find life, as the smitten children of Israel looked to the bronze serpent erected by Moses as a sign of God's grace. Then the text leads naturally to the best loved passage of Scripture, John 3:16-17, the heart of the gospel. The Spirit of God is seeking you out to make you his own. The Greek word "anothen" (v.3) has a double meaning -- "anew" or "from above." Tragically, the "born again" movement of the 1960's interpreted "anothen" as "born again." The word "again" is used to describe how one can be accepted into the Kingdom without being baptized. However, according to the New Testament and this passage in particular, Jesus describes salvation as a gift of God's Spirit given through the "water and Spirit" of baptism alone and does not imply any "decision," or "will" on our part. This text is for Trinity Sunday because it declares God to "be one". As our Father, He is behind all the good that occurs. As the Son, He is the revelation of love. As the Spirit, He is bringing us a new and eternal life in His Kingdom.
