What does John 3:4 mean?
Nicodemus doesn't misinterpret Jesus, or take a physical, literal view of His reference to being "born again." He asks this question because he knows Jesus did not intend a literal meaning. But Nicodemus is confused. Jesus is, in fact, referring to birth, but not a physical one. Rather, this is a spiritual birth.The term "born again" can become a cliché, but it's an important metaphor. Parents endure pain so their child can be changed and inherit their attributes. God endured our pain, in the form of Jesus on a cross, to give us a new birth (1 Peter 1:3). According to Scripture, being "born again" is an absolute, universal requirement for salvation (John 3:3). The gospel is offered to everyone, yet it is also exclusive: restricted to only a certain group. Only those who put their faith in Christ are saved. The gospel of John repeats this concept several times (John 3:5, 18, 36; 14:6).
