What does it mean that God hardens whomever he wills?

Romans 9:18 (ESV)

18 So then he has mercy on whomever he wills, and he hardens whomever he wills.

In short

That God hardens whomever he wills means

  1. he hardens whomever he pleases, regardless of whether they have done right or wrong; or

  2. when people go astray, God can use their sin to advance his own purposes.

When Paul writes that God hardens whomever he wills, he has in mind that God hardens whomever he wills without any consideration for a person’s good or evil actions. In other words, the thought here is that even before people are born, God might decide to harden certain people, which leads to their damnation, and this choice to harden is not based on whether a person has done good or evil.

Some contend that Paul has in mind that God might harden a person who is already insensitive to God in order to bring about his plans. It is argued that we know from Scripture that God does not tempt anyone to sin (James 1:13), and that he desires for all to be saved (1 Timothy 2:4). Also, it is said that in Exodus, Pharaoh was already hardening his own heart before God hardened his heart. This implies that Pharaoh was already straying from God before God hardened him. Yet this interpretation does not sufficiently wrestle with the fact that Paul speaks of the determinative will of God to emphasize the Lord’s action in hardening the heart. And it ignores that Exodus does not actually indicate that Pharaoh’s heart was hard before God hardened it.

So when Paul writes that God hardens whomever he wills, he means that God hardens whomever he pleases, regardless of whether they have done right or wrong.

Interpretation 1:
Paul teaches that God hardens whomever he pleases, regardless of whether they have done right or wrong.

Summary:

God can harden whomever he wishes. This means that God can use whomever he wants to further his plans.

Advocates:

  • James Dunn

  • Douglas Moo 

Minor differences:

Our authors agree that Paul is saying God can harden whomever he wills, aside from any considerations of what people have done.

James Dunn makes his interpretation clear when he rejects the idea that God hardened Pharaoh because he already hardened himself. That is, in the exodus narratives we learn that Pharaoh first hardens himself before God hardens him, but Dunn suggests that this thought has no place in Paul’s exposition. Rather, Paul’s whole point is that God hardens whomever he wills before they have done anything right or wrong (Romans 9:11).1

Douglas Moo agrees that Paul is teaching that God hardens whomever he wills aside from anything else that person has done. In particular, he contends that the outcome of hardening is damnation. Thus, since God sovereignly chooses, even before anyone has done right or wrong, whether or not he will harden their hearts, which leads to damnation, God sovereignly chooses before creation who will be created to be damned.2

Possible weaknesses

Interpretation 2:
When people go astray, God can use their sin to advance his own purposes.

Summary:

When Paul writes that God hardens whomever he wills, he has in mind the fact that God uses people’s sinful behaviour to his own ends. For example, at first Pharaoh hardened his own heart against God’s plan, but eventually God himself hardened Pharaoh’s heart to bring about the exodus. The point is that God has mercy on whom he desires and hardens whom he desires, to accomplish his purposes.

It is impossible to thwart God’s plans. God is sovereign over creation and the will of every human. This means God can have mercy on whomever he wills and harden whomever he wills to bring out his purpose. Thus, even those who live in sin are used by God to advance his goals.

Advocates:

  • Leon Morris

  • Frank Thielman

Minor differences:

Our authors agree that God would not harden someone’s heart who is not already hardening their own heart.

Leon Morris contends that God would never harden someone who has not first gone astray.8 Further, Morris says that God’s hardening of someone is always a punishment for sin. He notes that while God hardened Pharaoh, we should not think of this hardening as permanent. Rather, it could be that God relents from his hardening and then endures sinners with patience, waiting for them to repent.9

Frank Thielman agrees that God would only harden a sinner who is already sinning, contending that it would be nonsensical for God to harden someone to sin who was not otherwise sinning. For we learn in Romans 9:22 that God endures the wicked with much patience, which only makes sense if these are wicked by their own accord.10
