Well, I could keep on sparring, but I might as well cut to the chase: my bold, firm assertion is that this particular ramification of Calvinism is downright iniquitous. One can’t keep one foot in the biblical commands and another foot on the “question.” The latter will sow doubt — always.
God warned/lamented: “You thought that I was just like you!”
Be careful what you impute to God as “rational.”
"Unfair," maybe, but not wicked:
"As it is written, Jacob have I loved, but Esau have I hated. What shall we say then? Is there unrighteousness with God? God forbid. For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion." (Rom 9:13-15)
