The document describes Jesus' conversation with Nicodemus about how to enter the kingdom of God. Jesus tells Nicodemus that one must be born again or born of the Spirit. Nicodemus does not understand, so Jesus explains that fleshly birth will not grant access to the kingdom, but rather a spiritual rebirth is necessary. Jesus says God sent his Son not to judge the world but to save it, and that whoever believes in the Son will have eternal life.
