What does the phrase "god is just" mean, if the "just" part can't be contrasted to some kind of standard? Is there anything this god could wich would be branded "unjust", for example?
I think your hypothesis is small because your conception of "god" is small. Why would anyone believe in a "god" that is corruptible? Entrophy is a result of corruption and as a result all things in the physical universe break down. But the physical universe and time itself was born out of eternity by the Eternal GOD who made it in the first place. And He made it in stages, Day by Day, to reflect His Glory and perfection. "Thy Will be done on earth as it is in
eternal Heaven." We're simply just waiting for time to catch up with the perfect reflection of eternity for the perfect shall arrive as just as it was promised.
So what does the phrase "GOD is just" mean? It means GOD is eternal, without entrophy, and therefore without corruption. Injustice is corruption therefore God's Justice must also be Perfect, while our sense of justice is necessarily imperfect. Let's take man's perception and critique of God's fairness and justice and contrast it to God's answer to that hypothesis:
Ezekiel 18:23 "Do I have any pleasure at all that the wicked should die?" says the Lord GOD, "
and not that he should turn from his ways and live?
Yet you say, ‘The way of the Lord is not fair.’ Hear now, O house of Israel,
is it not My way which is fair,
and your ways which are not fair?
..... “Therefore I will judge you, O house of Israel, every one according to his ways,” says the Lord GOD. “Repent, and turn from all your transgressions, so that iniquity will not be your ruin
Again God says to the prophet:
Ezekiel 33:11 “Say to them: ‘
As I live,’ says the Lord GOD, ‘I have no pleasure in the death of the wicked, but that the wicked turn from his way and live. Turn, turn from your evil ways! For why should you die,
And the prophet and theist concludes:
The LORD
is righteous in her midst,
He will do no unrighteousness. Every morning He brings His justice to light; He never fails, But the unjust knows no shame.
- Zephaniah 3:5
And the Psalmist sings:
Righteousness and justice
are the foundation of Your throne; Mercy and truth go before Your face. - Psalm 89:14
GOD, out of His BIG heart,
did give us a standard - that standard is Christ in whom no iniquity or sin was found but lived a perfect life, a life of love for all mankind, dying for all of us sinner and saint alike and taking upon Himself our sins. He sent His beloved from His eternal domain to the earth to suffer and die in our place that we would be perfected in Him.
God has said: Why die in your sins O' man when your sins can be cast from you, as far as the east is from the west?
Still God does not coerce mankind but calls us in love to Himself, reasoning with us all.
"Come now, and let us reason together," says the LORD, "Though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall be as wool. If you are willing and obedient, you shall eat the good of the land; - Isaiah 1:18-19
He (the Christ) has come to give light to those who sit in darkness and the shadow of death, and to guide our feet into the way of peace.”
John 1:9-14
....the true Light which gives light to every man came into the world. He was in the world, and the world was made through Him, but the world did not know Him. He came to His own, and His own did not receive Him. But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.
The justice of God is that, despite our sins against a Holy God and against our fellow man, God in His mercy never gave up on us, impoverished as we are by our sins, but made a way through the cross to be perfected by His free grace. That my friend is justice. And as James says in James 2:12-13
"So speak and so do as those who will be judged by the law of liberty.For judgment is without mercy to the one who has shown no mercy. Mercy triumphs over judgment. "
Standing as a one whom God has had mercy upon and experienced His justice and goodness, Pat
