If you died today are you 100% sure you'd go to Heaven?

When presented with this question, many Christians will respond with "I hope so", or "Probably", and if you ask them why they will say "Well, I try to be a good person", or "I go to church and I forgive others". Well guess what: if you rely on your own works for an uncertain shot at salvation, you are not saved. This is because humans are fundamentally wicked. The Bible says that there is none righteous, there is none that doeth good. That is our state from our very beginning. Adam stood as God’s chosen representative of all mankind in the Garden of Eden, and when he fell, we all fell. It is through him that sin entered the world, and death and Hell are the consequences of sin. 

We can know how evil humanity is by looking first at God's moral law written in the Ten Commandments, and how we all break them all the time:

1.  Thou shalt have no other gods before me.

Have you ever not been a Christian? Have you ever elevated your own righteousness, wealth, fame, or earthly status to an idol? Have you ever doubted God or Jesus Christ? Then you have violated the first commandment, and you deserve Hell. 

2. Thou shalt not make unto thee any graven image.

Have you ever made or used a graven image of God, Mary, a saint, or a false god, and bowed down to it, served it, prayed to it, burnt incense to it, or kissed it? Have you ever used any medium between you and God other than Jesus Christ? Then you have violated the second commandment, and you deserve Hell. Using images as mediums between God and man is exactly what the Israelites did when they created the golden calf.

3. Thou shalt not take the name of the Lord thy God in vain. 

Have you ever said "oh my G-d", "on G-d", "G-d damn it", or "Jesus Christ" without fully revering in your heart the name of the LORD and of His one and only Son Jesus Christ? Have you ever sworn an oath on the name of the LORD without meaning it? Then you have violated the third commandment, and you deserve Hell. 

4. Remember the sabbath day, to keep it holy.

Have you ever worked on Sunday when you didn't need to, or when you could have devoted that same time to God? Then you have violated the fourth commandment, and you deserve Hell. God rested on the Sabbath and so should you. 

5. Honour thy father and thy mother. 

Have you ever disobeyed the authority of your parents? Have you ever broken the law when it wasn't required to protect your faith? Have you ever disregarded any legitimate authority? Then you have violated the fifth commandment, and you deserve Hell. 

6. Thou shalt not kill.

"Wow, I haven't done that one!" Jesus actually says "whosoever hateth his brother is a murderer". Have you ever hated your brother, a fellow believer, your neighbour, or anyone in your personal life? Then you have violated the sixth commandment, and you deserve Hell. 

7. Thou shalt not commit adultery.

Have you ever fornicated, or lusted after anyone that is not your wife? Have you ever divorced and remarried? Then you have violated the seventh commandment, and you deserve Hell. 

8. Thou shalt not steal.

Have you ever took that which is not yours, including committing intellectual plagiarism or refusing to pay debts? Have you ever withheld charity from the poor? Then you have violated the eight commandment, and you deserve Hell. 

9. Thou shalt not bear false witness against thy neighbour.

Have you ever said anything you knew was false about anything ever? Have you ever attacked someone using a claim you were unable to prove to be true? Then you have violated the ninth commandment, and you deserve Hell. 

10. Thou shalt not covet.

Have you ever felt envious towards something someone else has? Have you ever intentionally sought immense wealth and earthly glory? Then you have violated the tenth commandment, and you deserve Hell. 

If you answer "yes" to any of these questions, then you are vile (Job 40:4). You have committed a sin against an infinite God, and for that you deserve infinite punishment. This is how you know that if you rely on your own works even a little bit, you are not going to Heaven. No matter how good you think you are, you are not good enough in the eyes of God. So when you are asked of why you think you are saved, and you point to your prophesies, the devils you have cast out, and the many wonderful works you have done in the name of Jesus, what is stopping God from pointing to your sin that is ten times greater than your good works? 

But the story doesn't end there. You don't have to be good enough to go to Heaven, because Jesus already was. Jesus was conceived without sin, He lived a sinless life, and died a sinless death. He taught us how to act, how we must love even our enemies, and forgive those who trespass against us. He taught us about the kingdom of God and the glory which is to come. He rebuked evildoers and liars, and warned us about hell (over 50 times!). Because of that, they hated Jesus. They hated Him so much, in fact, that they had Him crucified. Jesus payed the price for our transgression so that we don't have to pay the price for our transgressions in Hell. Jesus has already fully secured the salvation of the faithful whom the Father has drawn; and Jesus will raise them up at the last day. This means that as long as you have faith, you are saved. The Bible actually says that we can know we are saved, stating in 1 John 5:13 "These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God." 

If you say this prayer and you believe from the bottom of your heart every word of it and you trust it to be true, then you can have 100% assurance of salvation:

Dear Jesus, I know that I'm a sinner. I know that I deserve to go to Hell, but I believe that You died on the cross for all my sins and rose again from the dead. Forgive me for my sins against You, please save me, and give me eternal life. I trust in you alone as my Saviour. Amen. 

Furthermore, once you are saved, not only can you know that you are saved, but you know that you can never not be saved. John 10:27–29 says "My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand." 

This is the greatest news you will ever hear in your life, whether you think so or not. 

Therefore, when someone asks you the question "If you died today are you 100% sure you'd go to Heaven?", the biblical answer is "Yes, because Jesus died on the cross for my sins, I trust in His death for my salvation, and I trust in God's promise that those who have faith are saved."
