So according to Calvinists, God is too weak to give man free will.
Unfortunately for your dogma, the bible teaches us that our eternal destiny depends on the choices we make.
Romans 2
6God “will repay each person
according to what they have done.”
7To those who
by persistence in doing good seek glory, honor and immortality, he will give
eternal life.
8But for those who are self-seeking and who reject the truth and follow evil, there will be wrath and anger.6
Gal 6
7Do not be deceived: God cannot be mocked.
A man reaps what he sows.
8Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit
will reap eternal life.
9Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.
Luke 12:47
47"And that slave who knew his master's will and
did not get ready or act in accord with his will, will receive many lashes,
48but the one who did not know it, and committed deeds worthy of a flogging, will receive but few. From everyone who has been given much, much will be required; and to whom they entrusted much, of him they will ask all the more.
