As for me, if anyone asks if they are going to heaven or hell or if they are “right with God,” my answer is for them to pray to God and get the answer from God himself for NO human being (including myself) has the qualifications and the credentials to judge the souls of others. I believe it is God’s and not other humans that should determine whether a person is “saved or not saved” or if they are “right or not right with God.”. The answer God gives is guaranteed accurate for God is perfect and flawless. Human beings are not perfect and are not flawless.
We should love one another as God loves us. It is not what a person looks like on the outside, but is who the individual person is on the inside that really matters
Actually Jesus did not call it heaven and hell but life and death, and He linked it to believing in Him and not believing in Him, and 1 John 3:14 quoted among the quotes below is pertinent to your OP:
John 3
14 But even as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up,
15 so that whosoever believes in Him should not perish, but have
everlasting life [G2222: zoe].
16 For God so loved the world that He gave His only-begotten Son, that whoever believes in Him should not perish but have
everlasting life [G2222: zoe].
John 5
24 Verily, verily, I say unto you, He that
heareth my word, and believeth on him that sent me, hath
everlasting life [G2222: zoe], and shall not come into condemnation; but is
passed from death unto life [G2222: zoe].
1 John 3
14 We know that we have
passed from death unto life [G2222: zoe], because we love the brethren. He that loveth not his brother abideth in death.
John 1
4
In him (the Word by whom all things were created and who is God)
was life [G2222: zoe]; and
the life [G2222: zoe] was the light of men.
1 John 5
11 And this is the record, that God has
given to us everlasting life [G2222: zoe], and
this life [G2222: zoe] is in His Son.
12
He who has the Son has life [G2222: zoe]; he who does not have the Son of God
does not have life [G2222: zoe].
1 John 5:20
20 And we know that the Son of God has come, and He has given us an understanding so that we may know Him who is true. And we are in Him that is true, in His Son Jesus Christ.
This is the true God, and the everlasting life [G2222: zoe].
Matthew 10
28 And do not fear those who kill
the body [G4983: soma], but are not able to kill
the soul [G5590: psuche]. But rather fear Him who can destroy both soul and body in "hell" [G1067 geenna].
I place the word "hell" in quotation marks because the KJV translates the Greek words haides, tartaroo and geenna all as "hell" but only geenna is the word used in the Greek text each time Jesus spoke of an everlasting death/destruction/perdition/damnation of the soul. The other two words translated as "hell" are haides and tartaroo, and are equivalent to the Hebrew word sheol, and are talking about the dwelling "place" of departed souls who are not in Christ.
Jesus told you that if you believe in
Him you have passed from
death to life, and said nothing about believing in this theology or that theology "getting you to heaven or hell". Jesus is a person, not a church or a theology.
-- take it from someone who rejects a lot of "Catholic" theology.
