Try This: Suppose that you were to die in ten minutes.
How sure are you that you will make it to Heaven.
Were you only 80% sure? 50% sure? Jesus said you can be 100% sure! But you have to be honest. Ok.
First... You have to admit that you are not good enough to get yourself to Heaven. “For there is none...good, no, not one,” it’s “not by works...which we have done,” and “all have sinned.” At least, that’s what the Bible says.
(Rom. 3:12, Titus 3:5, Rom. 3:23)
Next... Because we’ve sinned, we have to pay for breaking God’s law. “The wages of sin is death.”
Then... Jesus has already paid your debt of sin by dying for you, and He wants to give you eternal life. Just believe that His blood alone can save you. Repent of your sins and ask Him to forgive you, and He promised He would.
Finally... Just take God at His Word. He can’t lie. He’s God. Believe Jesus’ payment for your sin is the only way to Heaven, and you can say, “I am 100% sure I’m going to Heaven - because God said so!”
Just pray... Jesus, I admit I’m a sinner. I can’t save myself. I believe that your sacrifice has paid for my sins. I want to receive you as my Saviour, and I trust you to take me to heaven. Thank you for saving me! In Jesus' name, amen.
