I would say yes to everything you say, except I might have reason for issue with what
His character would be the very standard of justice.
It depends on what you mean by justice. His character is our standard of how our character needs to become, not only how we practice justice. Character is deeper than actions of justice.
I guess you could mean His character is the standard of how our nature needs to be in order to practice real justice. If this is what you mean, I agree. And I understand that we will be going through major correction of our character for the rest of our lives, and so we in this life will not be doing real justice like would really be good. But, at least, we in Jesus are growing in how God is transforming our character to be more and more like Jesus.
And so, then, God's ongoing process of such correction in us is real justice
What you basically mean by God, I would say, is possible.
And I find it quite a wonder, that there is any existence, at all. And we have conscious existence, too. And ones of us experience there being One such as God who is love and absolutely beautifully wonderful, plus almighty in immunity against any and all cruel and dominating feelings and emotions and evil, and kind and caring and sharing as family with us His children. It is a wonder, indeed, how He exists on His own and never started to exist.
And yet we have people who claim He does not exist. And these ones claim we humans are made only of material existent stuff. Yet, how ever did nonliving materials and energy forms evolve to make humans who can experience God as I have just described Him from my and other people's personal experience????
If material being is and started everything, then energy and matter evolved to make me and how I am able to experience God and be changed by this God from being a perpetual bully and then a religious self-righteous screwball and then trust in Jesus and get correction to seek how God turns me into a person who loves and cares for any and all people . . . more and more with this correction which is testified in the Bible (Hebrews 12:4-14, 1 John 4:17-18). I find it interesting how ones claim that dead material produced me with this conscious experience. I mean, by the way, that God is quiet, not silent; we need to be quiet and still and trust God to share Himself with us, but as He deeply corrects our nature so we become capable of personally sharing with Him. Then we can be personal in our caring, not only theoretical and ideological, not only trying to control people with our one-size-fits-all ideas and methods.
I don't think I got this from materials and how humans can be in how we relate. Material dependent and impersonal ways of dealing with people can keep us from sensing and sharing with God so we know He is.
And there is the noise of
"bitterness, wrath, anger, clamor, and evil speaking" and
"all malice" and unforgiveness > in Ephesians 4:31-32 > noise which keeps us from experiencing and enjoying God who is quiet in family caring and sharing and generously forgiving love.
So, of course, there is more to God, than your list has said.
