How is God just?
Let's suppose two men murder two women. Let's further suppose that one man is Christian, one man is not. Now, based on what I have been told the Christian man receives Grace and is allowed to enter heaven, while the non-Christian is sent to hell for all eternity.
Here's where I have problems:
First, if both men are guilty of the same crime, how is it just that they receive different punishments?
Hi! These are good questions. I cannot promise to make sense out of it for you, but what I will promise is not to gloss over it pretending it is easier than it really is. I also promise not to just make stuff up.
First of all, your question is best answered by the concept of the "economia" of God. Anglicizing that, we see God has an economy. We see reference to this over and over in Scripture, and a study of those portions would serve you well. There are some wonderful study aids on sites that have the Bible on line. It seems silly for me to post all of that here, so I'll move on to deeper concepts:
"Mercy and truth are met together; righteousness and peace have kissed each other." (Psalm 85:10)
You're concentrating on Judgment, condemnation, and "truth." What about Mercy?? Peace? I would rather re-direct your focus towards how utterly amazing it is that God can Love us, at all. That He can accept us, w/o condemnation. And I point out even Angels cannot fathom this.
If the punishment for this crime is eternal punishment then God allows the Christian to escape justice rather than enforce it. Furthermore, one woman's killer sees justice the other's does not.
Nope. Again, God's economia. Further,
If the punishment for the crime is that one must confess and repent
So's Law. Your misunderstanding is rooted in the fact of Communion of Saints, which has its beginning in all people who partake of the Passover doing so at the same "time." (In scare quotes because God transcends time, and He brings us into that in some specific ways, including those who keep the Passover as well as its modern day counterpart, Communion)
God's Judgment is Just. The problem is we don't always
see it. Thus:
"For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." (2 Corinthians 5:21)
Furthermore, if confession and repentance makes the balance of justice, what is the significance of Jesus' sacrifice?
NOW you're on to something! Further, what is the significance of partaking of Communion?
But beyond that, how do we know God is just? How is God just?
Mercy trumps Justice. Job found this out. We do not see this illustrated in every OT story, but in those that it is not, we see that it SHOULD be!
I will admit that with an understanding of God's Mercy, it is readily apparent that we are ourselves shielded from the horrors of Justice. It is within this revelation that the song Amazing Grace was written. This is fitting, because the Bible itself sums the whole thing up as a song.
