The Answer
If Calvinism is true, can your really blame the non-elect reprobate for their being rebellious against God?
After all look at the facts of the matter:
1. God punished them for the sin of Adam by making them be born totally unable to repent even when invited by God to do so.
2. God didn't really love them (salvifically), in fact he hated them from birth (i.e. Esau).
3. God didn't grant them what they needed to be saved.
4. God predetermined they would spend an eternity being tortured in hell prior to their even being born.
Can you really blame them for rebelling and hating that? Wouldn't you if you weren't chosen?
First, it does not matter whether we humans blame other humans, what matters is if God punishes humans for sinning, if God created them so that they could only choose to sin.
1. God does not punish anyone other than Adam for the sin of Adam. But sin has consequences, and the consequence of Adam sinning is that the many were made sinners, condemned to a state of separation from God. Thus as a consequence of Adam's sin, the many must believe in His Son or face eternity in a separated from God state, where they will be punished with torment for their volitional sins.
2. God loved fallen mankind in this way, He gave His Son so that whoever believes in Him shall not perish but have eternal life.
3. Anyone who hears and understands the Gospel of Christ has been granted the opportunity to be saved. However, some do not make a full blown commitment to Christ, rather they make a lip service commitment, a all gain and no pain commitment. Others try to fit Christ into their hearts, but leave conflicting and inhibiting desires in their hearts as well. But some, hear, understand, and trust in God and Christ from their heart, and rather than make Christ their highest priority, them make Christ their only priority, where anything that inhibits their full devotion to Christ is tossed as rubbish.
4. God predetermined that those whose faith He credits as righteousness will be put spiritually in Christ, regenerated, forgiven, be spiritually born again, conformed to the image of His Son and at His second coming, resurrected in glorified bodies, meeting Christ in the air.
Why muddy these waters with the silly traditions of men?
