In one minute I can explain to you how you can know for sure that if you died today you would go to Heaven.
All you have to know are 4 things.
1. God says,
"For all have sinned, and come short of the glory of God." Romans 3:23
If you're honest you know that you have lied. That's a sin. I'm a sinner. You're a sinner. All of humankind are sinners.
How did you become a sinner?
What is the price for your sin?
2. God says,
"...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
This is the story of Adam and Eve in the Garden of Eden. God told them they could eat of any tree but the tree of the knowledge of good and evil. They disobeyed God and ate from that tree. A sin was committed. That sin passed down to you and me. The price for sin, eternal death in Hell, also passed down to you and me.
3. God says,
"But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us." Romans 5:8
God loves you very much. He doesn't want you to go to Hell. In fact, He loves you so much that He sent His Son Jesus to die on the cross. Jesus actually lifts the sins from you and places them upon Himself. When they nailed Jesus to the cross, the blood that came from Him cleanses your sin. When He died on the cross He paid your price for sin, death. They buried Jesus but He arose from the dead conquering death and sin.
He offers you life.
"For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord." Romans 6:23
Eternal life is a present. You can't get water baptized to get into Heaven; be good to get into Heaven; pay money to get into Heaven; in fact, you can't do anything to get into Heaven, except repent of your unbelief and sin, trust Jesus' dying for you as your only way into Heaven.
4. God says,
"For Whosoever shall call upon the name of the Lord shall be saved." Romans 10:13
HERE IS HOW YOU CALL UPON THE LORD
Admit that you are a sinner.
Believe Jesus is the Son of God who came from heaven shedding His own blood for your sin.
If you are sorry for your sins and would like for God to save your soul, just ask Him.
I now admit that I am a sinner, going to Hell, and need You as my Savior. I now repent of my unbelief and cease to rely on myself, my church, my religion, my baptism or anything else that I might do to save or help save me. I NOW COMPLETELY TRUST YOU AS MY SAVIOR. Please forgive me of my sin and come into my heart today, JESUS, AND take me to HEAVEN when I die. Thank you for saving me.
In Jesus' name, Amen.
Just as you were born to your parents, you were born into the Kingdom of God when you called on Jesus.
