He was or is obligated to Himself? Based on what – higher power?
It was His justice that could not be left unsatisfied
What injustice was there to God? How can anyone cause injustice to God? Is God subject to injustice?
Does man's rejection of God "insult" Him? Does it hurt His "pride?"
Did not God design the world just as He wanted it, or was He surprized? If mankind acted the way He knew (and predestined, as you'd say) they would, where is the injustice in doing as God willed it? Or did we supercede His will?
None of this of course insults God, as God is not subject to passions. Man's disobedience only hurt man. And God, out of pure goodness and love, came down to salvage our miserable souls. Not because He needed to bring justice to Him (God is just with or without us, inspite and not because of us), but because He took pitty on ur miserable lot.
Kosta. You just don't get it. Your attempt to take a stab at what I was saying isn't even close to the mark.
On the first one, there is no higher power than God so stop being ridiculous. I said he was obligated to Himself. He's where it stops. God is a just God. He is holy. These are attributes of God which are basic.
God also has a will. With His will he exercises mercy where He wishes and doesn't where he doesn't want to. Yet, he can not violate His nature in doing so. That's the obligation to Himself. He can not violate who he is in accomplishing what He wants to accomplish. There is no higher power for him to answer to. He IS the authority - but He will be true to His nature.
God desired for a reconciliation between Himself and man. Yet, he could not allow man's sin to go unpunished without violating His justice. In order to meet the requirements of His justice, He made a way that the price for sin could be paid. That way was His very own Son. Christ took the penalty for our sin. God's justice was satisfied with the substituted offering, and His mercy poured upon us fulfilling His desire.
Such a picture of Christ's substitutionary death is shown throughout Scripture. From the blood of the lamb on the doorposts of the Israelis to the temple sacrifices, to the Ram in the thicket - God Himself provides the substitute offering to satisfy His justice. The wages of sin is death. Those wages must be paid if we are to have life. God paid them.
It is stupid to speculate about God being subject to injustice. Things don't happen "to" God. Things are permitted by God but all within His will. Nothing in this scenario makes God a passive participant in our salvation - so the idea of "injustice happening to God" even as a result of Himself is not even relevant. God would NEVER have violated his nature and so there is no discussion about God being unjust. God could have chosen to send us to Hell. His justice would have been intact. He wouldn't have poured out mercy, but mercy is a volitional aspect of God's will rather than a basic part of His nature.
God MUST BE just. He will not and can not violate His own just character. It is not possible for God to lie. It is not possible for God to be unjust. Mercy isn't in the same category. God exercises mercy where he will and whom He wishes to, He pardons. He's God. He can do that without violating His justice.
