Connieman,
With all due respect my brother, in my opinion, your question is an improper, hypothetical question and one that is unethical and a disappointment to Almighty God.
God does not choose some for Heaven and some for Hell. He has always known who His elect are and has left the choice to human beings.
When you follow Calvin's ideas you will come to the conclusion that God's love for His humanity is fragmentary because He is spoken of as loving unconditionally His elect and by default, hating the rest of these never-dying souls. His love for human beings is perfect just as His Divine attributes are blameless and unimpeachable. It is Divinely impossible for the Triune Godhead not to love that which They have created in the Image of God.
At both the Judgment Seat of Christ and at the Great White Throne Judgment God's justice will also be flawless. There will be no appealing to a higher justice, because there is none loftier than Christ's evaluation of our lives and the lost ones. All excuses for our behavior will be, as it were, thrown out of court. [Revelation 22:11].
No one would doubt His mercy. Christ's compassion/mercy is impeccable. His love, His justice, His mercy and holiness are inviolate and will forever remain the same. We are told that ‘He is the same yesterday, today and forever.' [Hebrews 13:8].
We could go on and speak of His holiness. Perhaps most of all we realize that God could never sin because this would be antithetical to His Essence of Being.
Loving humankind is the aspect of God's nature that is most spoken about by people. That is because we sense our utter need of His love even before the salvation experience. In actuality all of His Divine attributes are in blameless symmetry.
Sinners like to remind God's people that His love is so great that He will never send anyone to Hell. Why do they believe this? Because they are self-deceived and/or beguiled by the Evil one. When we over emphasize the love of God we place His justice in peril in the minds and hearts of both the people of God and also sinners. When we do this they think they are getting away with sinning, but as we both know they are not. Just as His love prevails so too His unrestricted judgment. Each of these concepts are Biblically factual.
If we push His sovereignty to the limit we get into all kinds of misrepresentations of the holy Gospel. For one, we make God the Author of evil. This is unthinkable in my mind and in the minds of many theologians. When we catapult sovereignty to the uttermost we make Him the autocratic God in Heaven who only cares for His ultimate glory, in damning Whoever He wills, when in reality He loves everyone and wishes that they would be saved eternally. [John 3:16 & I Timothy 2:4, 6].
In Romans 9:1-3 we notice that the Apostle Paul's desire was that his nationality would receive the ‘ . . . adoption . . ..' and become saved. [Romans 10:1] ‘Brethren, my heart's desire and prayer to God for Israel is, that they might be saved.' If Paul was speaking for God then we also must conclude that the Lord's desire is that all might be saved. We can rest assured that God would not allow Paul to state his wishes in the precious Word of God, if his feelings were contrary to His sovereign plan for human beings.
How can God be unimpeachable in His love, mercy, justice, sovereignty and holiness. He radiates these indivisible, inseparable, eternal attributes by offering the Gospel through His messengers and those who believe will be saved; those who remain in unbelief will be forever lost. [Mark 16:15-16].
