Dearly beloved congregation of our Lord Jesus Christ, if you have ever wondered about what is commonly known as "Calvinism" — in the popular understanding, the belief that God is ultimately in charge of everything, and that whether a particular human person is saved or lost comes down to God's choice to save that person, or not — how Calvinism can possibly be reconciled with your lived experience of human freedom, this text is the text for you. Just as the Apostle Paul is both the most famous and driven evangelist in history, and also the Bible's boldest teacher of God's sovereignty, so in the two verses before us this morning God not only dares to indicate that Pharaoh's heart is completely in God's power, but also deploys that truth as motivation for Moses to go and reiterate God's demands to Pharaoh. Yes, you heard that right. What this passage dares to assert is that God's sovereignty over the human heart should motivate us to evangelize our neighbors. God's sovereignty over the human heart should motivate us to evangelize our neighbors.
