My ways are not your ways, and My thoughts are not your thoughts."
Trying to figger out WHY GOD has set up the way things are is a fool's errand.
And anyhow, the quintessential voluntary nature of love makes refusal possible. We don’t see any direct equivalent in this mortal coil but we can see some parallels.
Love is God-centric in God’s economy. God is generous and forgiving, but things have to be done His way and so as to glorify Him, in order to receive the generosity and forgiveness. It is a narrow way, but not a robotic way (ranges of choice still exist). But it is also a powerful way.
