Real Urgency.
Today, I had lunch with a man I believe to be a living legend, Dr. Duke Heller. He’s likely the oldest living pioneer in the field of dental implants, a global award-winner, a published author, a generous influencer who’s shaped university dental programs, a mentor to high-profile college coaches, and a friend to some of the biggest voices in personal development.
But here’s the most powerful thing: Duke has used every bit of that influence not for his own glory, but to spread the love and truth of the gospel. He’s led thousands to Christ. Not just from the pulpits or conference stages he's spoken through, but through one-on-one conversations, right across the table from someone like me. At 87 he isn't slowing down. He's just released another book, speaking at more conferences than ever, and volunteering consistently with multiple outreach groups. I learned a lot today, but here are the top 3.
Wisdom from Duke:
1. Time is Short—And Eternity is Real.
I said that Dr. Heller is 87. He’s seen friends, family, and colleagues pass on. Some expectedly, others suddenly. The reality? Life is fragile. The days we’re given are uncertain and few. We must live with the urgency of eternity. Sharing Jesus isn’t something we can keep putting off. It’s the most important thing we can do.
2. One Bold Question Can Open the Door.
Duke looked me in the eye today and said, “Can I ask you a personal question?”
I said yes.
“Can you tell me the exact time you accepted Christ as your Lord and Savior?”
That question hit me. Not because I didn’t know the answer, but because of the power it carried. It can spark deep reflection on that moment or open a conversation that changes someone’s life forever. Sometimes, it only takes one Spirit-led question to shift someone’s entire eternity.
3. There’s No Time Left for Fear.
I spent years afraid to talk to friends and family about Jesus. I didn’t want to be “that guy” or seem weird. I was fine playing it safe. But now? I can’t imagine keeping quiet. I still struggle sometimes, especially with people close to me, but God is working on that in me.
And here’s the truth: we have the answer to eternal life. How can we justify keeping it to ourselves?
Duke gave me some of his personal resources today I plan to read. But more than that, he gave me a living example of selfless giving—of what it looks like to finish life well.
So why write this?
To honor a man who isn’t coasting into the sunset but sprinting across the finish line with purpose and passion. And to remind you (and myself) that we are called to live with real urgency. Our purpose isn’t just about this life. It’s about preparing ourselves and others for the life to come.
If you're like me—sometimes afraid, sometimes unsure—ask the Holy Spirit for courage and wisdom. He’ll give it. And when in doubt… be like Duke!
