When Jesus told Nicodemus that one must be “born” to see the Kingdom of God, the Pharisee’s reaction has often been explained as a linguistic misunderstanding — as if he confused the Greek word anōthen (“from above” / “again”). But if Jesus and Nicodemus actually spoke in Aramaic, that explanation falters, because the Aramaic expression has only one clear sense. Perhaps Nicodemus’ puzzlement lies not in a play on words, but in the very concept of birth itself.
Birth always implies childhood. No adult has ever been “born.” To be born means to begin again in the most dependent and vulnerable stage of life. This alone would strike Nicodemus, an older man and respected teacher, as impossible. How could a grown man become a child again? His response is not merely about physical logistics — re-entering a mother’s womb — but about the existential absurdity of applying “birth” to adulthood.
Here lies the deeper challenge. To be “born from above” means to enter the Kingdom as a child, because the Kingdom of Heaven is the Kingdom of children. Jesus himself taught elsewhere: “Unless you turn and become like little children, you will never enter the Kingdom of Heaven” (Matt 18:3). This childlikeness is not immaturity but dependence: openness, humility, trust. It is the posture of those who receive everything from God.
For Nicodemus, a learned and established leader, this was a stumbling block. Intellectuals and adults alike resist the idea of surrendering autonomy. We prefer to take matters into our own hands, to live as “grown-ups” who control our destiny. To become a child again feels like regression, weakness, even humiliation. And yet Jesus insists: unless you are willing to be reborn as a child of God, you cannot enter his Kingdom.
The contrast could not be sharper when we consider Hell. If Heaven is the Kingdom of children — total dependence on the Father — then Hell is the place of absolute self-autonomy. It is where humans insist on being fully in control, independent from God, even at the cost of their own ruin. Hell is the kingdom of the “self-made adult,” who clings to independence no matter how destructive it becomes.
History offers countless examples. Humanity discovered radioactivity and harnessed it for energy, gaining a sense of mastery over creation. But unlike God, who creates and sustains perfectly, human mastery is fragile and flawed. The same independence that built nuclear plants also produced meltdowns — real “living hells” for those affected. In this way, Hell is not fire God hurls upon us, but the flames of our own self-will, our insistence on ruling ourselves apart from God.
This is why Nicodemus struggled. Jesus’ teaching on rebirth was not a puzzle of vocabulary, but a demand for transformation: to relinquish adult pride and power, to re-enter life as a child utterly dependent on God. For some, this surrender feels like loss. In truth, it is the only way to gain life eternal.
