I would be interested to explore how a Calvinist who is not a supralapsarian would maintain their perspective of the Lamb’s Book of Life being completed by God unconditionally before the foundation of the world.
God knows everything infinitely, even sin, although He has never sinned, while man only knew about sin by trusting what God said prior to choosing to sin…
The very thing that makes love so romantic, mercy so tender, compassion so endearing, marriage so enchanting, and commitment so noble is the reality that the person could have chosen to do otherwise.
Man is a free moral agent with the ability to choose to sin or not to sin, which means that he is the efficient cause of sin, and thereby avoids the intrinsic revelatory problems of Calvinism and compatibilism with regard to the origin of sin and God desiring people to sin or be in hell.
Obviously, God does sincerely and self-sacrificially love even those who turn from His sacrificial provision, which is one of His most gracious, self-glorifying characteristics. A characteristic that many Calvinists are unintentionally undermining in an effort to promote their systematic interpretation.
