Did God need to have His righteousness increased?
Did God need to have His glory increased?
Did God need to increase His worthiness?
If not for us, then who did Christ die for?
You are intentionally dodging responding to my post. Responding will blow away the smokescreen of self-righteousness you've raised.
God was not obligated to sacrifice his Son on our behalf. To provide us with His righteousness (not our righteousness!) His glory (not our glory) His worthiness (not our worthiness!) and Sonship.
You see the Bible is very clear: we had no righteousness, glory or worthiness. They had to be credited to our account, and even the faith to believe had to be provided.
It is all the work of God, a work outside ourselves, a work that glorifies God alone. We had no part in our own adoption, no participation, no parity, there was no negotiation between parties. God adopted us out of sheer pity and mercy and restored us to Sonship. And only He and the Son get all of the glory for this work.
Dig into do your Bible and you can confirm all of this.
