Oh! I see what you are asking me now. The love between the persons of God isn’t exactly like it is for us. God esteems, has affections, takes pleasure in the Son. Likewise the Son for the Father. This reverberates between the two forming overflowing agape (Spirit). This one circle of love makes the one true God who is agape. Since it’s agape that always protects we can say it’s the one true God who protects us. You still haven’t touched the argument though. The Bible says that love always protects and that part of justice is to protect. If there is nothing in hell there’s nothing for God to protect His children from. Therefore evil is eternal and hell is eternal. God is outside time. He’s across time. The Bible says Jesus was slain from the foundation of the world. Yet it happened some two thousand years ago. God is “present” in all past present and future. His protective love and justice has been “always” going on in His timeless “NOW”
Here’s a way of putting it by Jonathan Edwards
It is a proper and excellent thing for infinite glory to shine forth; and for the same reason, it is proper that the shining forth of God’s glory should be complete; that is, that all parts of his glory should shine forth, that every beauty should be proportionably effulgent, that the beholder may have a proper notion of God. It is not proper that one glory should be exceedingly manifested, and another not at all…
Thus it is necessary, that God’s awful majesty, His authority and dreadful greatness, justice, and holiness, should be manifested. But this could not be, unless sin and punishment had been decreed; so that the shining forth of God’s glory would be very imperfect, both because these parts of divine glory would not shine forth as the others do, and also the glory of His goodness, love, and holiness would be faint without them; nay, they could scarcely shine forth at all.
If it were not right that God should decree and permit and punish sin, there could be no manifestation of God’s holiness in hatred of sin, or in showing any preference, in His providence, of Godliness before it. There would be no manifestation of God’s grace or true goodness, if there was no sin to be pardoned, no misery to be saved from. How much happiness so ever He bestowed, His goodness would not be so much prized and admired…
So, evil is necessary, in order to the highest happiness of the creature, and the completeness of that communication of God, for which He made the world; because the creature’s happiness consists in the knowledge of God, and the sense of His love. And if the knowledge of Him be imperfect, the happiness of the creature must be proportionably imperfect. - Jonathan Edwards
