Imagine you're standing before a judge, guilty of multiple crimes. The judge is about to pass sentence when he asks, "Do you have anything to say for yourself?" You stand up, look the judge in the eye and say, "Yes Your Honor, I believe that you're a good man... and because you're good, you will let me go." The judge will probably say something like, "Well, you're right about one thing... I am a good man. And it's because I am good that I'm going to see to it that you are punished for your crimes."
The very thing you are counting on to save you on the Day of Judgment (God's goodness) is going to be the very thing that will ensure that justice is carried out. Because God is a good and righteous judge He will make sure that every murderer, rapist and thief receive justice... but He won't stop there. He will also make sure every liar, blasphemer, and adulterer is punished. While this is something that is extremely tragic and far from God's ultimate desire for any person, the Bible is clear that the place of punishment for those who do not turn from their sins is Hell. Does the fact that you're headed for Hell concern you?
