Whoever Has the Son Has It All: Four Undeniable Reasons to Believe

Have you ever needed absolute certainty about something before you could rest easy? Some of us check the locks on our doors multiple times before bed, needing that confidence that everything is secure. In the same way, when it comes to matters of eternal significance, we need clarity. We need reasons to believe with confidence.

The Gospel of John provides exactly that—crystal-clear evidence that Jesus is who He claimed to be: God in the flesh. And this isn’t just academic knowledge. This is life-changing truth that demands a response.

The Power of an Undeniable Miracle

Imagine being unable to walk for 38 years. Nearly four decades of disability, of watching life pass by from the sidelines, of complete dependence on others. Then, in a single moment, everything changes. Jesus speaks, and a man who couldn’t walk for almost four decades stands up, picks up his mat, and goes home.

This wasn’t a gradual improvement. This wasn’t physical therapy showing results over time. This was instantaneous, complete, undeniable healing.

Yet remarkably, the religious leaders of the day missed the miracle entirely. They were so focused on their rules—their 39 categories of what constituted “work” on the Sabbath—that they couldn’t celebrate the fact that a man’s life had been transformed. They criticized Jesus for healing on the wrong day rather than marveling at His power.

How often do we do the same thing? We create expectations for ourselves and others about what the Christian life should look like, and when people don’t meet those standards, we become critical rather than celebratory. We focus on rule-keeping rather than life-changing relationship.

The truth is, nothing speaks louder than a transformed life. When someone who was bound by addiction becomes free, when a marriage on the brink of destruction is restored, when guilt and shame are replaced by forgiveness and freedom—these are the undeniable miracles that point us to Jesus.

Claims That Cannot Be Misunderstood

After healing the paralyzed man, Jesus made a statement that left no room for confusion: “My Father is working until now, and I am working.”

The religious leaders immediately understood what Jesus was claiming. God never stopped working, even on the Sabbath. His mercy, His grace, His sustaining power never took a day off. And Jesus was saying, “I work just like My Father works. I am one with Him.”

This wasn’t subtle. Jesus was claiming to be God.

The response was predictable: they wanted to kill Him. Not because they misunderstood, but because they understood perfectly and refused to believe.

Jesus continued making His identity unmistakably clear: “Whatever the Father does, the Son does likewise.” “I and the Father are one.” “All may honor the Son just as they honor the Father.”

These are not the words of a good moral teacher. These are either the claims of a madman or the truth from God Himself. As C.S. Lewis famously argued, we cannot simply call Jesus a great teacher while rejecting His claims to divinity. He didn’t leave that option open to us.

The question becomes: What if we’re wrong in our disbelief? What if Jesus really is exactly who He claimed to be?

Power That No One Else Possesses

Jesus didn’t just claim to be God—He demonstrated power that only God possesses. He spoke of greater works to come: raising the dead, giving eternal life, and executing final judgment.

“For as the Father raises the dead and gives them life, so also the Son gives life to whom He will,” Jesus declared.

This is staggering. Jesus wasn’t just a messenger pointing people toward life. He is the giver of life itself. He doesn’t simply help people improve; He brings the spiritually dead to life and promises to one day raise us physically as well.

Consider what Jesus said in John 14:6: “I am the way, the truth, and the life. No one comes to the Father except through Me.” Not “a way” but “the way.” Not “a truth” but “the truth.” Not “a life” but “the life.”

Jesus knows all circumstances, all thoughts, all motives. He has the authority and the power to judge because He is God.

And here’s the beautiful part: Jesus doesn’t hide from us. Like a parent playing hide-and-seek with a toddler, making little noises so they can be found, Jesus wants to be found. Jeremiah 29:13 promises, “You will seek Me and find Me when you seek Me with all your heart.”

Jesus made His claims boldly and clearly because He wants us to find Him.

The Ultimate Authority

Jesus used the title “Son of Man” for Himself, a direct reference to Daniel’s prophecy about the one who would receive “dominion and glory and a kingdom” that would never be destroyed (Daniel 7:13-14). Every Jewish person listening would have known exactly what He was claiming.

Jesus has ultimate authority. There’s no manager above Him to complain to, no higher court to appeal to. He is the final word.

And yet, even with all this authority, Jesus modeled perfect submission to the Father’s will. “I seek not My own will,” He said, “but the will of Him who sent Me.”

What would it look like for us to live with that same heart? To live as an audience of one, not trying to impress people or look good on social media, but simply seeking to please God?

The Estate Sale That Changed Everything

There’s a powerful story about a wealthy art collector who, along with his son, amassed priceless paintings—works by Picasso, Van Gogh, and other masters. When war came, the son went to serve and tragically died in battle.

On Christmas morning, a fellow soldier brought the grieving father a painting—not a masterpiece, but a simple portrait of his son. The father immediately hung it above the fireplace, moving aside millions of dollars’ worth of art.

When the father passed away, his will stipulated that all his paintings would be auctioned on Christmas morning. The auction began with the painting of the son. Only one person bid—a humble groundskeeper who offered ten dollars, all he had.

“Going once, going twice, sold!” the auctioneer declared. Then he announced the auction was over.

The crowd erupted in protest. “We didn’t come for some amateur painting! What about the masterpieces?”

The auctioneer replied, “According to the will, whoever gets the son gets it all.”

Whoever Has the Son Has It All

This is the heart of John chapter 5. Jesus made bold, unmistakable claims about His identity. He demonstrated unrivaled power. He revealed His ultimate authority. Why? Because He wanted everyone to know that He is God, and when you get the Son, you get it all.

You get forgiveness. You get freedom. You get eternal life. You get a relationship with the God who created you and loves you beyond measure.

The question isn’t whether Jesus provided enough evidence. He did. The question is: What will you do with Jesus?

“Truly, truly, I say to you, whoever hears My word and believes Him who sent Me has eternal life. He does not come into judgment, but has passed from death to life” (John 5:24).

The invitation stands. The evidence is clear. And whoever has the Son has it all.
