No Looking Back
Luke 17:20-37
Living With the Kingdom of God in Full View
Throughout human history, people have been consumed with trying to predict the future. We build calendars, track signs, and search for patterns, all in an effort to know what is coming next. Yet when it comes to the most significant event in all of human history — the return of Jesus Christ — no timeline exists. No date can be circled. No countdown clock is running. And that reality should stop us in our tracks.
In Luke 17, Jesus pulls back the curtain on the kingdom of God in a way that is both clarifying and deeply challenging. What he reveals is not a roadmap with specific coordinates, but a call to wholehearted devotion that shapes how we live every single day.
The Kingdom Is Already Here
When the Pharisees demanded to know when the kingdom of God would come, Jesus redirected their question entirely. They were looking for external signs, political upheaval, a dramatic shift in world power. Instead, Jesus told them that the kingdom of God was already in their midst. He was standing right in front of them.
This is a truth that changes everything. The kingdom of God is not simply a future event to be anticipated. It is a present reality rooted in the rule and reign of Jesus Christ. Where the King is, the kingdom is. And for those who have placed their faith in him, the kingdom of God lives within them right now.
The word the Gospel writers use for kingdom carries the weight of royal dominion, sovereign reign, and active kingship. It is not a passive concept. It is God's living, breathing authority at work in human hearts. The Gospel of Matthew references the kingdom 53 times. Luke references it 41 times. Mark, 17 times. In just three books of the Bible, the term appears more than 111 times. If the writers of Scripture returned to this theme so consistently, it demands our full attention.
The Danger of Indifference
Jesus draws on two of the most sobering examples in all of Scripture to illustrate what the days leading up to his return will look like: the days of Noah and the days of Lot.
What is striking about these comparisons is what Jesus does not say. He does not focus his warning primarily on the wickedness and depravity of those eras, though both were certainly present. Instead, he points to something far more subtle and perhaps far more dangerous: indifference.
People were eating and drinking. They were buying and selling. They were marrying and building and going about the ordinary rhythms of life. There is nothing inherently wrong with any of those things. The problem was that they were doing all of it in total disregard of God, living as though everything would simply continue on forever, with no thought of judgment, no thought of eternity, no thought of the kingdom.
James Edwards, an American theologian, captured it well when he wrote that people were attentive to daily business as though it would last forever and neglectful of eternity as though it would never come.
That description is not just a portrait of ancient cultures. It is a mirror held up to our own. We scroll and post, invest and harvest, build and consume, often with the same quiet assumption that things will simply continue as they always have. Jesus says otherwise. His return will be like lightning — sudden, unmistakable, and visible to all. There will be no opportunity for last-minute preparation. No time to get things in order. Alfred Plummer, a Bible commentator, described it plainly: none will foresee it and all will see it at once.
Remember Lot's Wife
Among all the warnings Jesus gives in this passage, three words stand out with particular weight: remember Lot's wife.
Lot's family was given a clear directive when the angels led them out of Sodom before its destruction. Do not stop. Do not look back. Lot's wife looked back. And in that moment, she was turned to a pillar of salt, as Genesis 19 records.
It would be easy to read this as a story about a single, fatal glance. But the look back was not mere curiosity. It was a longing. It was a heart still tethered to what was being left behind — the lifestyle, the possessions, the comfort, the familiarity of a life built around the things of this world. She had a divided heart. And a divided heart, when the moment of decision comes, will turn in the wrong direction.
You could take Lot's wife out of Sodom, but you could not take Sodom out of Lot's wife.
This is the heart of Jesus' warning. The kingdom of God requires wholehearted devotion. Not partial commitment. Not one foot in and one foot out. The Greek word Jesus uses for those who try to preserve their own life carries the idea of fencing something in, securing it as personal property, relying to the bitter end on earthly comfort. Jesus says that this path leads not to life, but to its loss. The one who lets go — who surrenders their grip on the things of this world — is the one who truly finds life.
Close Is Not Enough
One of the most sobering realities Jesus presents is that proximity to faith is not the same as faith itself. He describes two people in one bed, two women grinding grain side by side. When the day of the Lord comes, one is taken and one is left. The separation is not based on geography or association. It is not determined by who you sat next to in church or whose family you were born into.
Being close to someone who walks with God is not enough. Lot's wife was part of a family deeply connected to the covenant purposes of God. Yet connection to a faithful family, a faithful community, or a faithful church does not transfer salvation. It is received personally, by grace, through faith in Jesus Christ alone.
A Kingdom Worth Everything
The kingdom of God is not a place on a map. It is a relationship. It exists wherever people have enthroned Jesus as Lord of their lives. And those who carry that kingdom within them give visible witness to an invisible reality — in how they love, how they serve, how they treat others, and how they hold loosely to the things of this world.
Nothing in this life is truly safe unless it is placed in the hands of the Lord. The call of the gospel is not a call to lose what matters. It is an invitation to step into the life we were created to live.
The question worth sitting with today is a simple one. Are you ready? And are you looking forward to that day?
There is no looking back.
