The Tree That Cannot Feed You

There is a story about John Milton, the great 17th-century English poet, that is worth sitting with for a moment. In his epic poem "Paradise Lost," Milton imagines Satan and his fallen angels being transformed into serpents as punishment for their deception in the Garden of Eden. Consumed by a ravenous hunger, these serpent-angels discover a magnificent grove of trees laden with what appears to be beautiful, ripe, irresistible fruit. They throw themselves at it, biting and devouring greedily — only to find that every piece of fruit dissolves into nothing but bitter ashes and dust.

And here is the part that is most chilling: they keep coming back. Over and over again, they return to the same fruitless trees, hoping that this time it will be different. This time the fruit will be real. It never is.

Milton based this image on an actual plant — the Sodom's apple, a fruit that looks luscious and ripe on the outside but contains nothing but seeds and dry fiber within. It is a haunting picture. And it becomes even more haunting when we turn it inward and ask ourselves an honest question: How often do we return to things that look spiritually nourishing, things that appear full and healthy and life-giving, only to find that they leave us just as empty as before?

That is precisely the question at the heart of Mark 11:12-25.

A Parable in Action
As Jesus and his disciples travel toward Jerusalem, he spots a fig tree in the distance. It is full of leaves — healthy-looking, vigorous, the kind of tree that ought to have fruit on it. He approaches it hungry, expecting to find something that will satisfy. He finds nothing. Not because of drought, disease, or anything external. Mark tells us plainly: it was simply not the season for figs. By its very nature, this tree was never going to meet his need. It looked like it could feed someone. It could not.

Jesus curses the tree. And then he walks straight into the temple.

Mark structures this account deliberately, sandwiching the temple scene between two encounters with the fig tree. He wants us to lay one on top of the other and see them together. Because what Jesus finds in the temple is the same thing he found in the fig tree: the appearance of life with no fruit to show for it.

Leaves Without Fruit
The temple courts were full of activity. Money changers were swapping currencies so pilgrims could pay the required temple tax. Pigeon sellers were providing sacrificial offerings for those who could not bring their own. None of this was sinful in itself. These were legitimate, even necessary, services. But they had moved inside. They had set up shop in the court of the Gentiles — the one place where people outside of Israel could come and pray to the God of heaven.

And if merchants were conducting business there, one thing was certainly not happening: prayer.

This is the point. A flurry of religious activity had replaced genuine faith. The temple leadership had allowed — perhaps even encouraged — the transformation of a house of prayer into a house of commerce. And when Jesus quotes Isaiah, saying that the temple was meant to be a house of prayer for all nations (Isaiah 56:7), and then calls it a den of robbers (Jeremiah 7:11), he is not merely upset about the location of the marketplace. He is grieving the absence of faith.

No prayer. No faith. The tree is full of leaves and nothing else.

The Trees We Keep Returning To
It would be comfortable to read this as a story about first-century religious leaders and leave it there. But the warning is far closer to home than that.

Works righteousness does not always look like obvious, shameless rule-following. Sometimes it is subtle. Sometimes it looks genuinely spiritual. We live in an era when Christian content is more accessible than ever — podcasts, conferences, Bible studies, books, online communities. None of these things are bad. But there is a quiet, almost imperceptible shift that can happen in the heart.

At first, we engage with all of it because it helps us know and trust what Christ has done for us. Then, slowly, we begin to think that God is pleased with us because we do these things. The activity stops being the fruit of faith and becomes the foundation of it. The money changers have moved inside the temple, and we did not even notice.

This is the fruitless tree. It looks healthy. It looks full. It will starve you.

The Only Tree That Feeds
When Peter sees the fig tree withered from the roots the next morning, he is stunned. Jesus spoke one sentence, and the tree is gone. And hanging in the silence between Peter's astonishment and Jesus's response is the unspoken question: if the temple is the next thing to fall under that kind of judgment, where do we go? What do we hold onto?

Jesus answers with two words before anything else: "Have faith." But not faith in faith. Not faith in religious performance. Faith in God.

The confidence Jesus calls his disciples to in prayer is not something they manufacture through mental effort or spiritual discipline alone. It is grounded in something external to themselves. It is grounded in him. "Truly I say to you," he tells them. "Therefore I tell you." The fuel for mountain-moving faith is the word of the risen Son of God himself.

When we pray according to what he has told us to ask for — forgiveness, daily provision, deliverance from evil, growth in holiness, the coming of his kingdom — we can pray with a certainty that does not waver. Not because of what we have done, but because of who told us to ask and who guarantees the answer.

Milton imagined Christ clothing Adam and Eve not just outwardly with animal skins, but inwardly with his own robe of righteousness. That image captures something essential. There is nothing we can do to make ourselves more acceptable before God than we already are in Christ. And there is no sin we can commit that strips that away.

The tree that can actually feed us is not found in our own effort or activity. It is found in him. And unlike every other tree we keep returning to, this one never runs out of fruit.
