Would you go to heaven if you died today? Do you consider yourself a good person? Have you ever told a lie? What do you call someone that tells lies? Have you ever stolen anything regardless of the value? Have you ever used God's name in vain? Jesus said to look even look at man/women with lust is to commit adultery in your heart. Have you ever done that? Just by going through these 4 of the 10 commandments you are guilty of just at the least one if you are being honest. God says in his word that to break even one of these is the equivalent of committing all of them. If you were to stand before God today and he were to judge you based on this would you go to heaven or hell? Since there is nothing that you can do of yourself to be forgiven of your sins do you know what God did for you:
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. John 3:16
