should not perish
3:15 should not perish. In comparison, if any lost sinner would merely look in faith to the Lord Jesus, “lifted up” (John 12:32) to die in judgment for his sins on the cross, he also will not only not die, but will receive eternal life. If “ye must be born again,” then “even so must the Son of man be lifted up.” Genuine saving faith, therefore, involves belief in the deity of Christ (John 3:13) and His substitutionary death (John 3:14). It will then result in the new birth (John 3:7-8) and everlasting life (John 3:15).
