1. Experience
My every day experience lets me know I have free will. I reap what I sow. I can decide to do any number of things with my time right now. Even people who don’t think free will exists, betray it in their behavior. They constantly try to convince me I don’t have it! This is a blatant denial of their belief. Even their experience shows we have free will.
2. Philosophy
Most human philosophies postulate no free will. Atheistic, materialistic, evolutionary philosophy says we don’t have free will, we are products of our genes and must act the way we are coded to act. People don’t want free will. We like to think we are completely unaccountable victims. Unless you violate my rights, of course! Then those people should be held accountable. Experiencing thoughts of revenge and justice are a clear revelation that there is free will. It is one thing for a philosopher to say there is no free will; it is yet another to let people steal all the philosopher’s stuff, rape his wife, kidnap his kids, and so on and philosophically conclude, “Oh well, I’ll let it go, he had to do it, he didn’t have free will.”
3. The Bible
The Bible clearly shows we have free will. Whosoever will may come. Jesus would have gathered Jerusalem, but they would not. There is judgment and accountability, a reaping of what we’ve sown. The general theme of Scripture is one of rebellious free will acting out in hostility against God’s will. Yes there are passages like Romans 9 that say God can override our will, but this is not the norm. If it were the norm for God to override our wills, then why does Romans 9 focus in on Pharaoh? What makes Pharaoh an exceptional example?
4. Sin
The Bible says our heart is deceitful and desperately wicked. A denial of free will sounds exactly like something a wicked and deceitful heart would come up with. At the root of denying free will is a desire to get out of accountability. This is why atheistic evolutionary philosophy denies free will: now we can do what we want, no sin, I have to act this way, so get off my back. Free will does not sound like something people would come up with, and every time people come up with a theory, it typically denies free will. Sinful people do not like free will. It means we’re accountable and responsible to change and be better. It is much more freeing to pretend I have nothing to do with anything and all my mess is someone else’s fault.
5. Consequences
The best test of a theory is to see what would happen if everyone acted on it. Would you like to live in a society where we actually acted like there was no free will? There could be no law, no crimes or punishments, no judges, no juries, no sin. People would do “whatever they wanted” and no one could stop them. Who are you to stop what someone else cannot stop in themselves since they aren’t the ones in control anyway? What gives you the right to put your will above theirs? The result of actually, literally acting as if we have no free will would be absolutely destructive to life as we know it. Which is why no one acts like they don’t have free will.
6. Blasphemy
If there is no free will then God has to be the author of sin. God has to be responsible for all the evil in our world, all our sin, our genocides, the whole deal. Then for God to judge us for doing what He made us do? This makes God out to be a complete monster. Who needs Satan when God is this monstrous? If there is no free will then any revelation from God is completely irrelevant. There is no point for anything. All purpose, all beauty, all kindness, all joy is complete sham. God is a brutal dictator wishing demise on all those who are doing what they were programmed to do. If there is no free will; then God is not love.
You have free will. Judgment Day will make this painfully obvious. You should go ahead and admit it today and get yourself right with God through the Gospel of Jesus Christ and act as though you are someone who will give an account for every deed done in the body, because you will. And the defense, “I just did what you made me do” will be swallowed up in your inability to speak for the weight of your guilt before His glory.
