It might not say specifically, but what the heck do you think that this scripture means then?
John 3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him??
I mean come on, what is Jesus suppose to save people from and ONLY if you "believe" in him?
f thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, THOU SHALT BE SAVED. (Romans 10:9)
If you don't..John 3:36 says you won't see life but the wrath of God. According to the Bible there is heaven and hell.
Let's not forget John 3:16
16For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
Which means if you don't believe in Jesus you will NOT have eternal life- heaven or hell, rather simple to conclude where one goes if they don't believe (according to the Bible that is)
