A lofty goal. The agreement over Scripture is from other verses, correct?
To hold on to the good, it seems to me we should remember that God has created so in this time we have both light and dark, good and bad, belief and unbelief, truth and error, etc. Part of what guides my thinking is that we live in a creation with this reality, and we are going through an instructional phase created by God for His purposes.
Others seem to be fairly challenging you on whether or not your approach works well. As I read your above approach and what results from it, I repeatedly find myself asking whether you are misbalancing God's essence.
For instance, above you equate His Justness to His Righteousness. They are not the same thing but do work in perfect harmony in God. It's this perfect essence in perfectly unified attributes that we have difficulty understanding. Scripture does tell us He both loves and hates. Some explain away this hate replacing it with words like 'chooses" just as they explain His anger or hatred as anthropomorphism meant to help us understand. Others reason we can't have love if we don't also have hate - we need the dark to understand the light.
Years ago, I determined to come out of all the tradition I could shed and just let the Text say what it says, IOW let God say what He says. There was a teacher I read a few years ago who dealt with a Scriptural topic that is routinely argued about because, based upon other Scripture it can be viewed 2 ways. His resolution was that Scripture says both. That may not sound like great exegesis, but he was absolutely correct.
NKJ Isaiah 45:5-7 I am the LORD, and there is no other; There is no God besides Me. I will gird you, though you have not known Me, 6 That they may know from the rising of the sun to its setting That there is none besides Me. I am the LORD, and there is no other; 7 I form the light and create darkness, I make peace and create calamity; I, the LORD, do all these things.'
NKJ Isaiah 55:7-9 Let the wicked forsake his way, And the unrighteous man his thoughts; Let him return to the LORD, And He will have mercy on him; And to our God, For He will abundantly pardon. 8 "For My thoughts are not your thoughts, Nor are your ways My ways," says the LORD. 9 "For as the heavens are higher than the earth, So are My ways higher than your ways, And My thoughts than your thoughts.
I agree with working to harmonize Scripture. I have done a lot of personal work in the Text harmonizing in word studies to try to understand a word God uses as He uses it rather than how Lexicons or others define it. So, one of my guides as I said earlier is to let God say what He says and work to understand what He means. One of the basic hermeneutics we all should know is the retention of context.
The other harmonization it seems is your first lofty goal based upon our KING'S lofty prayer. Maybe we should just relax a bit and read those 2 above quoted sections of Isaiah repeatedly until we realize we're unharmoniously fighting - which is not good debate - over things that are above our current abilities and that this lack of capacity will likely last until He returns.
FWIW, I'm seeing some fighters trying to take deep breaths and reign in the ad hominem and suggest to others that this would be better. We've all got internal issues, but a unified Body is His will and prayer. What and Who's more important?
