Do you know for sure that you are going to heaven when you die? The Bible tells us in 1John 5:13: These things have I written unto you...that ye may know that ye may know that ye have eternal life,...
Dear Friend, one day you are going to die, and your body will be buried. But you have a never dying soul that will spend eternity in heaven or hell.
The word of God teaches us that we must realize some certain things in order to go to heaven.
First: You must realize that all of us have sinned.
For all have sinned and come short of the glory of God. (Romans 3:23)
Second: There is punishment for sin.
For the wages of sin is death... (Romans 6:23a)
the Bible is specific: Wherefore as by one man sin entered into the world, and death by sin; and so death passed upon all men for that all have sinned: (Romans 5:12)
That one man was Adam. The moment he sinned against God, he died spiritually. That same death has passed upon us when we first sinned. The Bible tells us in John 3:3 ...except a man be born again, he cannot see the kingdom of God.
If we die physically in this condition, having never been born again; (Revelation 20:14-15) And death and hell were cast into the lake of fire. This is the second death. And whosoever was not found written in the book of life was cast into the lake of fire.
Third: Jesus paid the penalty for our sins.
God loves us very much and sent His Son Jesus to die in our place.
But God commendeth His love toward us, in that, while we were yet sinners, Christ died for us. (Romans 5:8)
When Jesus died on the cross He paid your debt for sin by taking your punishment upon Himself.
...but the gift of God is eternal life through Jesus Christ our Lord. (Romans 6:23b) For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. (Ephesians 2:8 - 9)
Salvation in heaven is a gift to be received by faith in Jesus, trusting Him completely. We cannot earn a gift, we do not deserve a gift; we must accept a gift.
Fourth: Trust Christ to save you today.
If you realize that your sins have condemned you, and that Jesus is the only One who can save you, call on Him right now trusting Him with all your heart to save your soul. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. For whosoever shall call upon the name of the Lord shall be saved (Romans 10:10,13)
To call on the Lord right now, pray something like this from your heart:
Dear Jesus, I know I am a sinner; I know I deserve hell for my sins. I believe You died for me, and I am trusting You to save my soul and give me the gift of eternal life. Thank you Jesus for saving my soul. Amen.
