The Line Isn't Where You Think — Loyalty Is What Divides Everything

The 1971 Coca-Cola ad: a vision of everybody different, together, at peace — and the sermon's argument that the only path to that world runs through the one line Pepsi could never find.

The Turn

Pepsi thought the dividing line was flavor. Most of us think the dividing line in Christianity is belief, or behavior, or belonging to the right group. The sermon exposes that the line is loyalty — and once you see it in 1 Samuel 18, Luke 14:26 stops sounding harsh and starts sounding like the clearest thing Jesus ever said.

The Setup: Coke, Pepsi, and the Wrong Dividing Line

The 1971 "I'd Like to Buy the World a Coke" ad secured a generation of market dominance not because Coke tasted better, but because it sold an identity. Pepsi responded with the Pepsi Challenge in 1975 — blind taste tests at amusement parks — because they believed the dividing line was flavor. They were wrong, and they never recovered. When you misread where the line is, you get everything wrong. That's the setup for 1 Samuel 18.

1 Samuel 18: Seven Pairs of Eyes

The Hebrew word for "eye/assess" appears seven times in the chapter — people are constantly sizing up, deciding, taking stock. Four times David is called "successful" (the same Hebrew root as wise, prosperous, and blessed by God). Everyone in this story is a public actor; their choices are visible and carry political weight. The Lord's hand is on David, and the text keeps saying so.

Jonathan's Gamble

Jonathan, heir to a throne God has already said won't continue — though who outside of Saul and Samuel knows that is an open question — strips off his royal robe, his armor, his sword, and gives them to David. In public. Everyone understood what it meant: the prince had thrown his loyalty to the shepherd boy. This is not sentiment. It's a high-stakes political and personal decision made by someone whose own father will eventually try to kill the man he just endorsed.

Saul's Misread and the Spear

The women's victory chant — "Saul his thousands, David his ten thousands" — was a conventional form of praise, not a slight. Any person in that culture would have heard it that way. But Saul can't interpret anything generously because he knows the Lord's blessing has left him, and he's operating in low-grade defiance of that fact. So the song lands as an insult. He starts watching David. Then throws a spear at him. Twice. David dodges both times and goes back to playing the lyre, because he's still young enough to stay in the room for round two. An older man wouldn't.

Love Is Loyalty

Six times in the chapter someone is said to love David. Jonathan, Michal, all the people, Saul's own servants. Toby points out that in the ancient Near East, "love" in political and treaty contexts meant loyalty — not personal feeling. Kings "loved" each other when they made alliances. Cities were "divided" when half loved one ruler and half loved another. The question the chapter keeps asking is: where does your loyalty land? Saul's answer: enemy, continually.

Luke 14:26: The Same Line

The sermon's hinge: Jesus says if you don't hate your father, mother, children, spouse, even your own life, you cannot be his disciple. That sounds brutal until you've just spent time in 1 Samuel 18. "Hate" here means lower loyalty — not emotional contempt. Jesus isn't asking you to despise your family. He's saying he cannot be fifth in line. If he's anywhere but first, he's nowhere. There is one throne in a human heart, and only one thing fits on it. Everything else that competes for the top spot is finally just another version of yourself sitting there — your priorities, your comfort, your people arranged to serve your wants.

The Landing

The unity that Coke ad keeps selling — different people, at peace, singing together — only comes through one door: Jesus as the uncontested, uncompromised line. Not race, not class, not nationality, not flavor. Toby's son, without warning, held up a Coke and said, "It's the real thing." Thirty years of preaching, and the ending walked in on its own.

1. The Coca-Cola ad made Toby tear up a little, and he admitted it. What is it about that image — all those different people on a hillside, singing — that still gets to you?
2. Toby said Pepsi failed because they misread where the dividing line was. They thought it was flavor. In 1 Samuel 18, what did he say the actual dividing line is, and how does the text make that case?
3. The Hebrew word for "love" shows up six times in 1 Samuel 18, and Toby said in that world it meant loyalty — like a treaty, throwing your hat in with someone. How does that reading change what you hear when Jesus says to "hate" your father and mother in Luke 14:26?
4. If you mapped out your actual hierarchy of loyalty — not the one you'd say out loud in church — where does Jesus honestly land?
5. Toby said that putting kids or parents or a spouse above Jesus is really just a socially acceptable way of keeping yourself on the throne. Does that ring true for you, or does it feel like too much of a reach?
6. Jonathan made a public loyalty decision to David even while his own father was throwing spears at the man. The stakes were real and the cost was visible. What would it actually cost you to make that same kind of clear, visible loyalty decision to Jesus right now?
7. Toby said the unity that Coke ad was selling — all those different people, at peace, together — only comes through drawing the line at Jesus and nowhere else. If that's true, what would have to change about how this church actually functions for that to be real and not just something we say?
8. Name one specific loyalty in your life — not a category like "family" or "work," but a named person or thing — that you've been placing above Jesus. This week, say it out loud to someone you trust and tell them where it needs to move.
