So, God is indebted to mankind to save all or provided opportunities for all to potentially become saved? On what judicial basis do you blaspheme the living God for being "unrighteous, partial and unjust"? What is the judicial basis for your accusation that God is partial?
True story: Just yesterday I read a very sad story about a woman who abused her NINE (9) small children by forcing them to live in squalor, filth, hunger, malnourishment and overall poor health. Meanwhile, other kids with other families have it much better. Explain to me how God is "unrighteous, partial and unjust" for decreeing that the nine kids have the kind of broken home and a grossly irresponsible and unloving mother on one hand, while on the other He also decreed in eternity that many other kids have a much better lifestyle with better parents.
Or...more true stories from the bible: How was God "unrighteous, partial and unjust" in decreeing in eternity that Issac and Jacob would participate in the inheritance of the Abrahamic Covenant, while rejecting Ishmael and Esau from this same covenant.
Do you realize that fallen man God had set up on earth before all angels - the fallen and the elect - to learn from man what they see fallen men doing?
