Trusting the God Who Finishes What He Starts

Summary of my sermon, based on Luke 13:18-35. Preached at Greenhills Christian Fellowship Toronto on February 8, 2026.

In our last look at the Gospel of Luke, Jesus healed a woman on the Sabbath. This sparked a confrontation with the local synagogue ruler, setting the stage for a broader conflict with the Pharisees. As Jesus gained prominence, the Jewish leaders grew increasingly concerned. This explains one of the major themes in Luke: why the gospel eventually turned toward the Gentiles and how the Jewish leaders came to reject Jesus.

Jesus begins addressing this by asking, “What is the kingdom of God like? And to what shall I compare it? It is like a grain of mustard seed that a man took and sowed in his garden, and it grew and became a tree…” He then compares it to a tiny bit of leaven that a woman hides in flour until the whole batch is leavened (Luke 13:18-21, ESV).

These parables teach that God’s kingdom starts small but grows into something massive. Look at human history: the British Empire was once the largest to ever exist, yet today it is a shadow of its former self. That is the limit of a human-made kingdom. Christianity, conversely, started with a carpenter and twelve fishermen in a backwoods town. Today, it is a global phenomenon—a miracle only God could accomplish.

There is a second message here regarding how long this growth takes. The early Jews expected a sudden, dramatic military redemption, hoping for a leader to free them from the Roman Empire. Because Jesus didn’t fit that mold, they missed His signs. They were stuck in their own mindset of how God was supposed to work.

It is easy to fall into that same trap. Many of you might be waiting on God right now—for healing, for work, or for restored relationships. We must not get bogged down by our own expectations. As Psalm 27:14 (ESV) reminds us, “Wait for the LORD; be strong, and let your heart take courage; wait for the LORD!” God is sovereign. He might not answer on your timeline, but He will provide what is for your good.

Those who wait and trust in the Lord will enter what Jesus calls the “narrow door.” When asked if only a few will be saved, Jesus said, “Strive to enter through the narrow door. For many, I tell you, will seek to enter and will not be able” (Luke 13:24, ESV). The Jewish people largely believed everyone born a Jew would be saved automatically. But Jesus gives a brutal teaching: admission to God’s kingdom is exclusive, not based on heritage.

He warns that many will claim to know Him, but He will reply, “I do not know where you come from. Depart from me.” They will see Abraham, Isaac, and Jacob in the kingdom while they are cast out. Yet, their exclusion means our inclusion. God promised Abraham that in him all families of the earth would be blessed. People from the east, west, north, and south will recline at the table.

Despite this rejection, Jesus still had incredible compassion for His people. When warned that Herod wanted to kill Him, Jesus refused to back down. Instead, He mourned for the city rejecting Him: “O Jerusalem, Jerusalem, the city that kills the prophets and stones those who are sent to it! How often would I have gathered your children together as a hen gathers her brood under her wings, and you were not willing!” (Luke 13:34, ESV).

God’s patience is incredible, giving us chance after chance. But we cannot mistake His patience for universalism—the belief that everyone will eventually be saved. There comes a point where a choice must be made. You are not saved just because you go to church. What saves you is faith in Jesus Christ alone. As Jesus said, “I am the way, and the truth, and the life. No one comes to the Father except through me” (John 14:6, ESV).

If you don’t know Christ, I pray you come to know Him today. For those who do trust Him, remember Philippians 1:6 (ESV): “And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.” Trust in Him, for He is always worthy of our faith.

I Will Follow

Summary of my sermon, based on Luke 9:51-62. Preached at Greenhills Christian Fellowship Toronto on November 17, 2024.

If you were a Christian in the 90s, you probably remember the WWJD bracelets—short for “What Would Jesus Do?” This phrase has deep roots in Christian history, tracing back to Charles Spurgeon in 1891. However, it became mainstream in 1896 when Charles Sheldon used it as a tagline in his novel “In His Steps.” His idea was to look to Jesus as a moral example in daily life, which helped birth the Social Gospel movement—an effort to apply Christian ethics to social issues.

This is a good thing. James 1:27 tells us, “Religion that is pure and undefiled before God the Father is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world.” Likewise, 1 Peter 2:21 states, “For to this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps.” However, the WWJD movement also had its flaws, primarily its commercialization and oversimplification of discipleship.

Following Jesus is not just about wearing a bracelet or making a moral decision in a single moment—it is a lifelong commitment that requires sacrifice. Luke 9:57-62 presents three responses to discipleship that highlight its demands.

First, Jesus tells a man who eagerly volunteers to follow Him, “Foxes have holes, and birds of the air have nests, but the Son of Man has nowhere to lay his head” (Luke 9:58). This reveals that following Jesus may require giving up security and comfort. Many missionaries, like Robert and Sheila Cousins, have left everything to serve Christ. Even Christian leaders such as John Piper and Tim Keller could have pursued more wealth and success elsewhere but chose humble service instead.

Next, Jesus responds to another man who wants to delay discipleship until after burying his father: “Leave the dead to bury their own dead. But as for you, go and proclaim the kingdom of God” (Luke 9:60). This shocking statement underscores that following Jesus must take the utmost priority. Matthew 6:33 reminds us, “But seek first the kingdom of God and his righteousness, and all these things will be added to you.”

Finally, Jesus warns against looking back when called to follow Him: “No one who puts his hand to the plow and looks back is fit for the kingdom of God” (Luke 9:62). Discipleship requires focus. Hebrews 12:1-2 exhorts us to “run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith.”

Ultimately, we cannot do this on our own. Jesus set His face toward Jerusalem, resolved to go to the cross for our salvation (Luke 9:51). When the Samaritans rejected Him, James and John wanted vengeance, but Jesus rebuked them, teaching mercy. He was on a mission to save both Jews and Samaritans, showing us that His path leads to the cross and the mercy of God. 1 Peter 1:3 reminds us that we have “a living hope through the resurrection of Jesus Christ from the dead.”

So, what sacrifices do you need to make to follow Christ more fully? How can you rearrange your life to better reflect His kingdom?
