What is Molinism and is it biblical?

from the old testament

• God is fully sovereign. In Isaiah 46:9–10, God says that He is the One “declaring the end from the beginning and from ancient times things not yet done, saying, ‘My counsel shall stand, and I will accomplish all my purpose.’” God chose what would happen from the very beginning—before anything existed. His knowledge and will are unified because His plans stand by His own authority.
• Psalm 135:6 agrees, saying, “Whatever the LORD pleases, he does, in heaven and on earth, in the seas and all deeps.” God’s actions flow from His sovereign pleasure, not from foreseen human decisions. Nothing in these passages suggests that His works are defined or limited by human choices, whether those choices occur in this world or in imagined alternative worlds contemplated in Molinist middle knowledge.
• Supporters of Molinism sometimes appeal to 1 Samuel 23:11–12. In that passage, David asked the LORD whether the men of Keilah would surrender him to Saul if he stayed in the city, and God revealed that they would. Molinists argue that this shows God knowing multiple potential outcomes in which an individual’s decision determines which becomes true. Yet the context is simply God warning David about the city’s state of mind and the people’s fear of Saul. Revealing the natural outcome of staying in that situation was God’s means for protecting David.
• Another passage sometimes cited is Isaiah 48:17–19. There, God tells Israel that obedience would have led to peace and blessing. Molinists use this to argue that God’s plans change based on human decisions—that if Israel had done X, God would have done Y. But the context is covenantal, with God explaining the real consequences of obedience and disobedience within the covenant He established.

from the new testament

• The issue raised by Molinism is whether God shapes His plan around what people would freely choose in any possible world, or whether His purposes determine the course of history. Scripture presents God as sovereign even over human decisions, including moral ones. Paul argued in Romans 9:15–18 that God has mercy on whom He wills and hardens whom He wills. God has complete freedom. God’s freedom doesn’t remove human responsibility, but God’s saving purpose is not dependent on human choice.
• Supporters of Molinism frequently appeal to Jesus’ words in Matthew 11:21–23, where He says, “Woe to you, Chorazin! Woe to you, Bethsaida! For if the mighty works done in you had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes.” Molinists argue that Jesus is pointing to that alternative world as the basis for God’s decision-making. But Jesus was not explaining the mechanics of God’s decree. He was announcing the seriousness of the people’s unbelief and demonstrating His perfect knowledge as the Judge who knows the actual condition of every heart.
• Matthew 23:37 is also sometimes used as additional support, since Jesus laments that Jerusalem was “unwilling” to come to Him. The argument is that people are acting contrary to God’s will, which Molinists claim supports libertarian free will. But His grief does not imply that God’s saving purpose was frustrated by human freedom. It simply affirms that people make real choices for which they are accountable. Jesus’ lament shows the reality of rebellion, not the limits of divine sovereignty.
• Scripture presents these truths together: humans are genuinely responsible for their moral decisions, yet God’s sovereign purpose remains certain. People are commanded to repent (Acts 17:30) and are held accountable for unbelief (John 3:19), yet those who come to Christ do so because the Father draws them (John 6:37, 44). Human responsibility is real, but it never overrides or restricts God's purposes.

implications for today

“Who are you, O man, to answer back to God? Will what is molded say to its molder, ‘Why have you made me like this?’ (Romans 9:20).

If we had a modern equivalent to Paul’s question today, it might be “Who do you think you are?!” That question is meant to put an upstart in his place. And, in fact, many of us act like upstarts when we start questioning God. Curiosity is fine. Challenging God’s purposes and wisdom is not.

In fact, trying to find answers to the unanswerable can lead to wrong answers (even if the motives are good). One such unanswerable question is, ”How can God ordain everything and yet I be responsible for what He ordained that I would do?” Scripture presents this tension, but doesn’t tell us how it works. So we trust in God. God is sovereign, and we are just creatures. We aren’t in a position to challenge Him based on our limited understanding.

This is one reason regular Bible reading is so important. While it doesn’t reveal all the answers to us, it does reveal that we can trust and depend on our sovereign God. His plan is the perfect plan—even though we may not understand it.
