Summary of my sermon, based on Luke 11:13-23. Preached at Greenhills Christian Fellowship Toronto on Good Friday – April 18, 2025.
We just read the familiar story of the crucifixion of Jesus, and while it would be easy to linger there, our sermon series, Journey to Jerusalem, moves us to Luke 11:14–23. Surprisingly, the themes in this passage actually echo what we just saw at the cross. Here again, Jesus performs a miracle—casting out a demon from a mute man. It’s not the first time we’ve seen this, and by now, in Luke’s Gospel, it almost feels routine. But something has shifted. The opposition to Jesus isn’t just skeptical anymore—it’s growing hostile.
Instead of marvelling or asking honest questions, some begin accusing Jesus of being in league with demons. In Luke 11:15, they say, “He casts out demons by Beelzebul, the prince of demons.” Others aren’t as aggressive but still resist belief, saying in verse 16, “while others, to test him, kept seeking from him a sign from heaven.” Both reactions still exist today. Some accuse Jesus or Christians of being harmful or deluded. Others say they’ll believe if God just proves Himself—on their terms.
We saw this same mindset at the cross. The crowd scoffed, “If you are the Christ, save yourself!” The soldiers mocked, “If you are the King of the Jews, save yourself!” It’s a mindset that makes faith conditional: “I will believe in Jesus if He gives me what I want.” Whether it’s wealth, healing, or a specific answer to prayer, the demand is the same—“Do this, and then I’ll believe.”
But Jesus doesn’t operate on our terms. Who are we to demand a sign from God? In fact, in Luke 11:29, He says, “This generation is an evil generation. It seeks for a sign, but no sign will be given to it except the sign of Jonah.” Sign-seeking is not faith—it’s bargaining. And God doesn’t negotiate salvation. He gives it freely by grace, through faith. Ephesians 2:8–9 makes that clear: “For by grace you have been saved through faith… not a result of works.”
And that’s what this is—works-based belief. “I will believe when…” is just another way of earning your way to God. But faith doesn’t wait for proof. Faith says, “God is able… but if not…” Just like Shadrach, Meshach, and Abednego said in Daniel 3, even if God doesn’t do what we ask, we will still trust Him.
And here’s the thing—people who demand a sign often move the goalpost. Even if Jesus had stepped down from the cross, those mocking Him would have just asked for something else. Just like Pharaoh in Exodus who saw ten plagues and still hardened his heart. If your faith depends on your demands being met, you’ll never be satisfied.
On the other end, some claim Jesus isn’t the only way—they say He’s one truth among many. That’s the spirit of postmodernism: all truths are equal, and no one can claim exclusive truth. But Jesus confronts that thinking. In Luke 11:17–19, He logically dismantles the idea that He casts out demons by Satan’s power. A kingdom divided against itself cannot stand. And by that same logic, postmodernism crumbles. If everything is true, then nothing is true.
Jesus doesn’t leave room for multiple truths. He says in John 14:6, “I am the way, and the truth, and the life.” That’s not a suggestion. It’s a claim. And it’s either true or it isn’t—there’s no middle ground.
Finally, Jesus closes this section with a powerful phrase in Luke 11:20: “But if it is by the finger of God that I cast out demons, then the kingdom of God has come upon you.” The finger of God—just like in Exodus, when the magicians of Egypt saw God’s power and could no longer deny it. Jesus is stronger than any enemy. He’s not just another voice in a crowd of opinions. He is the King who conquers, the Truth who saves, and the God who calls us to believe—not on our terms, but on His.
