The Bible is emphatic on its teaching that humans possess free will and are capable of originating evil. Notice, for example, that in the very first chapter of the Bible God commands humans to be fruitful and exercise dominion over the animal kingdom and the earth (Gen. 1:26). The fact that God must command us to carry out his will reveals that we are not forced to carry out his will. We can choose to obey God or not, as the subsequent narrative makes clear.
Human free will is manifested in the fact that, throughout Scripture, God gives us choices and calls on us to choose the way he knows is best. To give just a few illustrations, notice the way God talks to the Israelites when finalizing his covenant with them at the end of Deuteronomy:
See, I set before you today life and prosperity, death and destruction. For I command you today to love the Lord your God, to walk in his ways…then you will live and increase, and the Lord your God will bless you in the land you are entering to possess. But if your heart turns away and you are not obedient, and if you are drawn away to bow down to other gods and worship them, I declare to you this day that you will certainly be destroyed…I have set before you life and death, blessings and curses. Now choose life, so that you and your children may live…(Duet 30:15-19).
God gives the Israelites a choice to either choose life (which means choosing to love and obey him) or to choose death (which means rejecting him). God obviously hopes they’ll choose life, but it is ultimately up to them to decide. In a world that is centered on love, even God can’t be guaranteed to always get what he wants.
Another clear example of the Lord placing choices before people, calling on them to choose to follow him, is found in Ezekial 18.
If a man is righteous and does what is lawful and right….he shall surely live, says the Lord GOD….The person who sins shall die….But if the wicked turn away from all their sins…they shall surely live; they shall not die.
Having laid out the choices before us, God discloses his own feelings about the matter when he asks:
Have I any pleasure in the death of the wicked, says the Lord GOD, and not rather that they should turn from their ways and live?… Cast away from you all the transgressions that you have committed against me, and get yourselves a new heart and a new spirit! Why will you die, O house of Israel? For I have no pleasure in the death of anyone, says the Lord GOD. Turn, then, and live. (Ezek. 18:5,9, 20, 23, 31-32).
The Lord makes it emphatically clear that he doesn’t want anyone to perish. He takes no pleasure in the death of the wicked. He rather wants everyone to embrace the life he offers them. But because love must be freely chosen, he cannot simply decree that he will get what he wants. He pleads with people to turn to him, but he will not coerce them.
Another way Scripture reveals that humans are free is by depicting them as the originators of their own free actions. For example, Jesus’ taught that, “The good person out of the good treasure of the heart produces good, and the evil person out of evil treasure produces evil; for it is out of the abundance of the heart that the mouth speaks” (Lk 6:45, emphasis added). Similarly, Jesus taught that it was out of the person’s own heart that “evil intentions, murder, adultery, fornication, theft, false witness, [and] slander” arise (Mt 15:19). These are not things that God in any sense desires or intentionally plans. They originate in a persons’ own heart.
Evil originates in us, not God. To give just a few more illustrations, we could cite King Solomon (I Kgs 11:6, 9), King Rehoboam (2 Chron 12:14), and King Zedekiah (2 Chron 36:12-13). Jerusalem degenerated to such a low moral point during the time of Jeremiah, according to the Bible, because God’s people had “a stubborn and rebellious heart” and had “turned aside and gone away” (Jere 5:23, emphasis added). In frustration, the Lord asked them, “How long shall your evil schemes lodge within you? (Jere 4:14, emphasis added).
Because agents are genuinely free, many things God wills don’t get accomplish, and many evils God wishes could be prevented take place. Yet, because God is infinitely wise and retains over-all control of the cosmos, we can rest assured that his promise to eventually overcome all opposition and achieve his purposes will come to pass.
