Calvinists hardly argue against these verses and these verses are pretty strong to debunk Calvinism.
Hebrews 10:29 “Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?”
Notice that there are these people who have done despite unto the spirit of grace. Christ did not just die for the elect, He died for lost sinners too. In v29, these people are lost people who have that have greater damnation and Christ died for them.
2 Peter 2:1 “But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.”
‘denying the Lord’: these are lost people and Christ died for them too.
These 2 verses show that Christ did not just die for the elect, He died for lost people too.
God does not enforce one’s heart to do good and another person’s heart to do evil. Calvinists will pull tons of verses to prove that God moves a person’s heart to do an evil deed such as God hardened Pharaoh’s heart.
Psalms 33:15 “He fashioneth their hearts alike; he considereth all their works.”
God does it fairly with everyone, fashioned it according to their wants. However their hearts move, God fashions it in a way that will bring glory to his name.
Revelation 3:20 “Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.”
The tying knot to show us it depends on how much we open our hearts to the Lord. What door is God knocking? Inside our hearts. God is knocking not the door of our heart and He can’t go in and lead us to do the right things unless we let Him in.
However our heart moves, God fashions it in a way that will bring glory to His name.
Here’s the idea, a man’s heart can only be more good or evil depending on how much he opens his heart to the Lord. If our heart wants to do good things (free choice first), the Lord’s going to fashion and move that heart to become even more good and more good for His glory. It’s the same thing with evil. If we say no to the word of God, then the Lord fashions that heart to that free choice of man where he wants to do evil and He will harden that person’s heart like Pharaoh or He will move them, deceive them into a lie on what they want to do and make them commit even more atrocious sin. Why? Because God is a type of god who will give mankind what they want. That proves even more on free will, that God doesn’t make everything happen.
Foreknowledge
We believe that God is all-knowing, which is called foreknowledge.
Calvinist will argue that if God already knew something was going to happen, how can He know that something is going to happen and then a person does it after that, that God is not in control of that? If all these events had occurred, God knew they were going to happen, they say that God is responsible for these things. Calvinists combined foreknowledge with God making it happen/predestination/God’s counsel. Because of God’s foreknowledge knowing that it’s going to happen, then obviously He made it happen.
The way to debunk this is easy: assume that we went to this fortune teller and he says that our car is going to get blown up and we laugh about it saying that it’s not going to happen and we walk out and go to the car but all of a sudden the car blows up and we’d go, ‘Man, that fortune teller was right, with great power of foreknowledge’. But then we found out that the fortune teller made it happen, then we’re going to go, ‘His foreknowledge is weak, it’s not foreknowledge, it’s a fraud!’.
So if God made it happen, it’s not foreknowledge, it’s fraudulent.
If we put foreknowledge with predestination, we automatically disprove an all-knowing God.
Total Depravity
Calvinists believe in total depravity, in other words, man is unable to do good. That’s why they believe that God elected us to be saved because He forced something inside us, made us believe in Jesus, and put something good inside us, and made us do it. Because out of our own strength and ability, we’re unable to do good. That’s why they believe that lost man is not capable to do good unless God does something in them.
But these verses disprove that, it shows that lost sinners are able to do good.
Romans 2:14-15 “For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)”
God implanted everybody with a conscience that convicts them so that they’re able to do good so that God can rightly judge them.
‘Your conscience thought of a good thought, your conscience convicted you to do this good thing but your free choice rejected that so you’re held responsible, not God, for the consequences of that action.’
Luke 6:33 “And if ye do good to them which do good to you, what thank have ye? for sinners also do even the same.”
Notice the verse says that sinners are capable of doing good.
Matthew 7:11 “If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?”
(same as Luke 6:33) These evil people are capable of doing good things.
