Steep:
Yes Hell and heaven are real but telling people hell and heaven is real without mentioning what Jesus has done to save them is not the gospel. The gospel is about Jesus Christ and him cruicified.

1 Corinthians 2:2 For I determined not to know any thing among you, save Jesus Christ, and him crucified.

When the holy Spirit came upon the apostles they went about preaching Jesus.

Jesus said the Spirit will bear witness and reprove the world of sin.

The fear of hell fire will not prevent you from entering into it.


Jesus said many would strive to enter into the kingdom but would not be able.

Luke 13:24 Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.

There are many people today who are genuinely striving to make heaven but alas they will fail, why because they go through the wrong way.
The only way is faith in Jesus and his finished work on the cross.
John 10:9 I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.

Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:

2:9 Not of works, lest any man should boast.

The grace of God only save a man that trust in Jesus and his finished works.

Secondly, salvation does not just mean making heaven, No, this is unbiblical in fact there is nothing like making heaven but there is something called Eternal life, having the righteousness of God.

Salvation means God saving our whole being first our Soul/Spirit and then our body at his appearance.

Salvation is about God making us a whole new creation, a creation created unto good works, a life of union with God, to be in God's kingdom.
God's kingdom is about righteousness and joy in the Holy ghost this kingdom is born in us when we are saved.

Some people try to separate being born again from being saved, both are the same you cannot be saved if you are not reborn however, this rebirth is done by God not by man.

When you trust in christ and his finished work God recreate you a new this is called the new birth.

So dear reader the gospel is a wonderful news it is God offering you redemption, forgiveness, regeneration, his own righteousness and eternal life, however all these things are in and through Jesus christ.
