What does John 3:4 mean?
What is the meaning of John 3:4?

How can a man be born when he is old?

– Nicodemus hears Jesus say, “Truly, truly, I tell you, no one can see the kingdom of God unless he is born again” (John 3:3).

– He thinks only of physical realities: years lived, bodies aged.

– Scripture shows that age never limits God’s work: Abraham was “about a hundred years old” when Isaac was promised (Romans 4:19), and yet God fulfilled His word.

– The Lord consistently calls people, regardless of stage in life, to start fresh: “Even to your old age I will remain the same” (Isaiah 46:4).

– Jesus’ call to new birth is therefore timeless, echoing promises like “Today, if you hear His voice, do not harden your hearts” (Hebrews 3:15).


Nicodemus asked.

– His honest inquiry mirrors many who wrestle with spiritual truth (Mark 9:24; Acts 8:31).

– Nicodemus, a respected teacher (John 3:10), underscores that intellect and religion alone cannot grasp the kingdom; revelation is needed (1 Corinthians 2:14).

– God welcomes genuine questions that lead to deeper understanding, as demonstrated when Jesus gladly explains rather than rebukes (James 1:5; Isaiah 1:18).


Can he enter his mother’s womb a second time

– Nicodemus’ literal picture shows the limits of human reasoning about divine realities (Proverbs 3:5).

– His confusion parallels the Samaritan woman who thought only of natural water (John 4:11) and the disciples who thought of physical bread (Matthew 16:7).

– By exposing the impossibility of physical re-entry, Nicodemus unknowingly sets the stage for Jesus to unveil a spiritual birth “of water and the Spirit” (John 3:5).


to be born?

– The question emphasizes absolute need: if physical rebirth is impossible, another kind of birth must exist.

– Scripture reveals this new birth as the sovereign work of God: “He saved us through the washing of rebirth and renewal by the Holy Spirit” (Titus 3:5).

– It produces a new creation (2 Corinthians 5:17), brought forth “not of blood, nor of the will of the flesh, nor of the will of man, but of God” (John 1:13).

– The impossibility Nicodemus imagines highlights that salvation is entirely grace-driven, “With man this is impossible, but with God all things are possible” (Matthew 19:26).


summary

Nicodemus’ literal questions open the door for Jesus to contrast natural birth with a Spirit-wrought new birth. Age, intellect, and physical ability offer no access to God’s kingdom; only the miraculous, grace-filled work of being “born of water and the Spirit” grants entry. What seems impossible to man becomes gloriously possible through the saving power of God.

Why is being 'born again' necessary for seeing the kingdom of God?
