Jesus's most famous parable is usually read as a lesson about hearers: some reject the word, some are shallow, some are distracted, some bear fruit. That reading isn't wrong, but it misses what the parable is actually organized around. The missing piece changes what a church should do.

Hearken; Behold, there went out a sower to sow: And it came to pass, as he sowed, some fell by the way side, and the fowls of the air came and devoured it up. And some fell on stony ground, where it had not much earth; and immediately it sprang up, because it had no depth of earth: But when the sun was up, it was scorched; and because it had no root, it withered away. And some fell among thorns, and the thorns grew up, and choked it, and it yielded no fruit. And other fell on good ground, and did yield fruit that sprang up and increased. (Mark 4:3-8)

Count the parts. The parable has one seed, one sower and four soils, and every variable in it is held constant except the ground the seed lands on. Since the seed and the sower are the same everywhere, the differences in outcome, from zero to a hundredfold, are entirely explained by the condition of the soil. Jesus was teaching about environment.

Three of four failures are environmental

The wayside. The ground is hard and trodden. The seed can't penetrate; the birds take it. In Jesus's explanation, Satan cometh immediately, and taketh away the word that was sown in their hearts (Mark 4:15). The word never got in, because the surface was packed.

The stony ground. Here shallow soil lies over rock. The seed germinates at once and grows fast, then withers under the heat. They have no root in themselves, and so endure but for a time (4:17). What failed was the depth of the soil.

The thorns. The soil looks good, since the seed grows, but it's crowded with competitors that choke it. The cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word (4:19). The environment is full of other things.

The good ground. Where seed and soil match, the yield is enormous.

In no case does the seed fail or the sower get the blame. Three of the four failures are conditions of the ground. Ground can be worked.

The prophets said the same

The Old Testament had already used the image as an instruction.

Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the LORD. (Hosea 10:12)

For thus saith the LORD to the men of Judah and Jerusalem, Break up your fallow ground, and sow not among thorns. (Jeremiah 4:3)

Break up your fallow ground. The prophets' command is "prepare the soil." Neither of them says "receive better seed." Fallow ground (hard, unworked, thorn-infested) has to be broken before sowing, or the sowing is wasted. The work comes before the seed.

And Psalm 1's righteous man is defined by where he's planted: he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season (Psalm 1:3). Put the tree by water, in the right location and environment, and fruit follows.

What the church does instead

The modern church has poured almost all its energy into seed: better preaching, better teaching, better curriculum, and more conferences, more content, more sermons, more media. The assumption underneath all of it is that if the word is delivered clearly enough and often enough, fruit will follow. When it doesn't, the hearer gets the blame for being hard-hearted, shallow or worldly.

But the parable says the seed was already good and the sower was already sowing. What determined the outcome was the ground. A church that delivers seed to unworked ground, week after week, is doing what the parable describes, with the same sower and the same seed and predictable losses to the wayside, the rock and the thorns.

The prophets would ask a different question. Where we ask whether the sermon was good, they would ask, "What's the condition of the soil these people live in?"

What soil is

Translate the image, and the "ground" a person's faith grows in is their environment. That means the relationships they're embedded in, the rhythms of their week, the people who know them, and the settings in which the word is repeated and applied and tested. The individual's inner disposition is part of the soil, but so are the surrounding conditions that make depth possible or impossible.

The wayside is a person whose life is so trodden by the traffic of noise, hurry and distraction that nothing can penetrate. The word is heard and gone before it lands.

The stony ground is a person with genuine enthusiasm and no depth of relationship to root in. They respond immediately and wither at the first heat, because nobody was near enough to hold them through it. No root in themselves is what Jesus says of them. Nobody was there to lend them one.

The thorns are a life so crowded with cares, riches and other things that the word has no room. A life like that can be friendly to the word and still too full for it.

The good ground is a life in which the word is received into a network of relationships that repeat it, apply it, and correct its application. There is depth there because there are people, and the thorns get cleared because someone helped clear them.

The design of the church is a soil-preparation program. It calls for daily contact (Acts 2:46), and for mutual teaching, so the word is heard many times from many mouths (Colossians 3:16). Burden-bearing keeps the heat of trial from scorching the rootless (Galatians 6:2), confession names and pulls the thorns (James 5:16), and hospitality gives the trodden ground rest and space. The one-anothers are the breaking up of fallow ground.

Why the sermon alone cannot do it

Preaching, however excellent, can't substitute for soil, for a reason written into how human beings learn.

Retention requires repetition spread over time. It requires retrieval, meaning you're asked to reproduce what you learned. And it requires context, because what's learned in one setting transfers poorly to a setting unlike it. A word heard once, in a room unlike the life it's meant to govern, from a person who won't ask you about it, is seed on the wayside.

A word heard on Sunday, repeated Tuesday at a table by a friend, applied Thursday in a conversation about a real problem, and tested Saturday when the friend asks how it went, is seed in good ground. The seed was the same. Only the soil was different, because it had been worked.

Paul knew the division of labor: I have planted, Apollos watered; but God gave the increase (1 Corinthians 3:6). Planting and watering are both human work done to the ground. God gives the growth to worked soil.

The exercise

Take the four soils and map your congregation onto them honestly. How many members live on the wayside, so hurried that nothing lands? How many are stony, enthusiastic and rootless and one crisis from withering? How many are thorned, sincere and crowded out? How many are in good ground, embedded in relationships that repeat, apply, and test the word?

Then ask the prophets' question about what it would take to break up the fallow ground. Most churches would reach for a better sermon. The prophets would change the conditions people live in, with smaller circles, more frequent contact and someone near enough to hold them under the heat.

The seed is fine and always has been, so go and work the soil.
