The way to be assured of going to Heaven when one dies is simply to trust in Jesus Christ alone for one’s eternal salvation. Accept Jesus Christ as one’s only Savior. Faith alone in Christ alone.
He is eternal God, the second Person of the Trinity, who became incarnate. Without ceasing to be God, He took on Himself true humanity. He did this in order to die on the cross in payment for our sins.
As He hung on the cross, our sins were judicially imputed or ascribed to Him. Our sins were poured out on Him and judged by God the Father. Jesus Christ paid the penalty for our sins.
The Bible tells us to accept Jesus Christ’s finished work on the cross (His substitutionary atonement in payment for our sins) as the only way of salvation.
It’s worthless to rely instead on our own works (or a mix of faith and works) to save us.
John 6:28-29
Then they asked him, “What must we do to do the works God requires?”
Jesus answered, “The work of God is this: to believe in the one he has sent.”
2 Corinthians 5:21
For He (God the Father) has made Him (Jesus Christ) to be sin for us (He was judged for our sins, He died as a substitute for us), who knew no sin; that we might be made the righteousness of God in Him.
John 3:16-18
For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He who believes on him is not condemned: but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
John 6:47
(Jesus Christ said) He who believes in me has everlasting life.
John 10:28-30
I give them eternal life and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all, no one can snatch them out of my Father’s hand. I and the Father are one.
Acts 4:12
And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.
Acts 16:31
Believe in the Lord Jesus and you will be saved...
Ephesians 2:8-9
For by grace you are saved through faith and this is not from you, it is the gift of God. It is not from works, so no one may boast.
1 John 5:11-12
God has given us eternal life, and this life is in his Son. He who has the Son has life; he who does not have the Son of God does not have life.
Acts 10:43
Every one who believes in him receives forgiveness of sins through his name.
Romans 4:7-8
Blessed are they whose transgressions are forgiven, whose sins are covered. Blessed is the man whose sin the Lord will never count against him.
John 11:25-26
(Jesus Christ said) I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die. Do you believe this?
Jesus Christ in His own words:
“I am the bread of life; he who comes to Me shall not hunger, and he who believes in Me shall never thirst.”
John 6:35
“I am the light of the world; he who follows Me shall not walk in the darkness, but shall have the light of life.”
John 8:12
“I am the gate; if anyone enters through Me, he shall be saved, and shall go in and out, and find pasture.”

“I am the resurrection and the life; he who believes in Me shall live even if he dies.”
John 11:25
“I am the way, and the truth, and the life; no one comes to the Father, but through Me.”
John 14:6
“I am the true vine, and My Father is the vinedresser.”
John 15:1
“Truly, Truly, I say to you, before Abraham was born, I am.”
John 8:58
“But what about you?” he (Jesus) asked. “Who do you say I am?”
Simon Peter answered, “You are the Messiah, the Son of the living God.”
Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven.”
Matthew 16:13-17
Amen to all you said. When I initially responded to your post I got sidetracked. What I intended to say was that God’s free gift of Eternal Salvation through faith in Jesus Christ is so enormously generous and wonderful as to defy description. I think Paul’s statement in 2nd Corinthians Chapter 9 may be the UNDERSTATEMENT of the Ages, seeing that the gift is eternal, never-ending joy and bliss in God’s perfect FOREVER in a brand new Universe wherin there has never been any sin.
2nd Corinthians 9:15 Thanks be unto God for his unspeakable gift.
2Peter 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
