I don't need a basis to love my son. I assume you do not either, since you state that you would be disconsolate to the end of your days if your beloved boy stood (rightfully) accused of a heinous crime. God doesn't need a basis to love us criminals either.
The basis for LOVE is value.
Love does not (and cannot) exist APART FROM value.
A value is either imputed (you project it out onto something) or inherent (it is intrinsic to the nature).
Let's go simple.
Water.
We are mostly comprised of water. Without water we cease to exist. We perish without access to water. Right?
Water=Life.
What about water that has been polluted, then? (Can you tell an analogy is coming up?)
Poisoned water is useless to humans as a means of supporting life.
Would you value poisoned water THE SAME as you did fresh water?
No!
Here comes the analogy.
You can't LOVE your (polluted, poisoned) son the same as a non child molesting no murdering son. You'd be imputing value to him on a basis rooted in a past context and not a current one or future one.
Meaning what?
The engine driving VALUE is the fundamental way to understand the emotion of LOVE.
You are asserting (imputing) value to a son when his state-of-being (actual value) is no more based on the resonance of a past status and not a present of future one.
Consequently, what you view as LOVE is nothing more or less than a deliberate self-blindess. It has no basis in fact.
I'm trying to explain this rationally to you. You are responding emotionally and ignoring the actual basis for emotionas which is VALUE driven.
As status changes, value changes. As value changes, emotion driven value must change.
I feel like I've been over and over this and I'll bet you feel the same way.
YOU'RE ASSERTING a ridiculous situation in which God doesn't have a basis for His actions rooted in reality.
Things are what they are. To treat them otherwise is to act delusionally.
The basis for God's desire to have man conform to a Righteous Standard is to bring man into alignment with an ACTUAL state of being.
Otherwise, neither man's status (in God's eyes) or the reality of man's actions has any import whatsoever. This would nullify the legal Justice of God's condemnation of man IN THE FIRST PLACE.
If God condems based on a reality and status quo, then, God must exonerate the same way.
Can't you recognize that? Otherwise, God is guilty of using crooked scales of Justice "rigged" for exculpation.
