Why does the same gospel produce such different responses in different people? Jesus addresses this very question in His parable of the sower (Matthew 13:1–23; Mark 4:1–20; Luke 8:4–15). A farmer goes out to sow his seed, which Jesus identifies as the Word of God. The seed falls upon four different kinds of soil, representing four different responses to the Word. Notice that the sower scatters the seed freely, without first determining which ground is most likely to produce a harvest. This is how we are called to proclaim the gospel. We preach Christ indiscriminately, to everyone, without attempting to determine who is elect or who might respond favorably. The same gospel is proclaimed, with the same promises and the same call to repentance and faith. Yet the results are dramatically different. The difference lies in the soil, which represents the condition of the human heart. And there is a vast difference between hearing the gospel, making an outward profession of faith, and actually being born again.
The first soil is the hardened pathway. Here the seed falls upon ground so hard that it never penetrates. The birds come and quickly devour it. Jesus explains that this represents the person who hears the Word but does not understand it, and Satan snatches away what has been sown. There is no saving response, no repentance, no faith. He may follow the words well enough at an intellectual level, but the message is not received with spiritual understanding. This reminds us of what Paul teaches in 1 Corinthians 2:14, that the natural person does not accept the things of the Spirit of God because they are spiritually discerned. The problem goes far deeper than a lack of information. The sinner’s heart is naturally opposed to God. He needs far more than persuasion. He needs a new heart.
The second soil is the rocky ground, and here things become more deceptive. The seed springs up quickly, and initially everything looks promising. Jesus tells us that this person receives the Word immediately and even with joy. Think about that. There is an enthusiastic response, perhaps accompanied by tears, a public profession of faith, baptism, and involvement in the life of a church. To those looking on, this may appear to be a wonderful conversion. Yet Jesus says there is no root. When tribulation or persecution arises because of the Word, the person falls away. Luke records that such people “believe for a while” (Luke 8:13). There is a temporary faith that looks very much like the real thing, yet it differs in kind from saving faith, and testing exposes it. The initial joy may have been sincere as an emotional experience, but it was not evidence of genuine regeneration. This is why we must never confuse enthusiasm for Christianity with the new birth. Emotional responses may accompany genuine conversion, and often do, but they cannot establish that conversion has actually occurred. As 1 John 2:19 explains, those who finally depart from the faith demonstrate that they never truly belonged to Christ.
The third soil presents another danger, perhaps even more subtle. Here the seed falls among thorns, and the plant begins to grow. There is a response to the Word, and outwardly there may be every appearance of Christian faith. Yet as time passes, the cares of this world, the deceitfulness of riches, and the desires for other things choke the Word, and it proves unfruitful. Unlike the second soil, Jesus does not specifically say that this person falls away. Indeed, such a person may remain outwardly attached to a church for many years. The problem is that the heart is increasingly occupied with other things. Christ does not have its supreme affection. The things of this world, many of which may be perfectly legitimate in themselves, have become more important than the things of God. This person may still profess faith, but no mature spiritual fruit is produced. An outward attachment to Christianity, even one that lasts for decades, is no guarantee that someone has actually been born again.
Then we come to the fourth soil, and here everything changes. This person hears the Word, receives it, understands it, holds it fast, and bears fruit with perseverance. Jesus speaks of different yields, thirtyfold, sixtyfold, and a hundredfold. Not every Christian produces the same amount of fruit, but every genuine Christian produces fruit. This is the only soil in the parable that represents a truly regenerate person. The fruit does not make the soil good. Rather, the good soil produces the fruit. This is precisely the relationship between regeneration and the Christian life. Good works are the evidence of salvation and never its cause: having been saved by God’s grace, we will bear fruit. The fruit may vary greatly in its abundance and maturity, and genuine believers still struggle with remaining sin. Nevertheless, where God has granted spiritual life, that life will become evident.
What accounts for the difference between the fourth soil and the first three? We need to be careful here and allow Scripture to speak for itself. The story itself never tells us how the fourth soil came to be good. It describes the different responses to the Word and their outcomes. Yet Jesus does not leave the question unanswered. Between the parable and its explanation, the disciples ask why He speaks in parables. He replies that to know the secrets of the kingdom of heaven “has been given” to them, while to the crowds it has not been given (Matthew 13:11). Now notice how Jesus describes the soils. The person on the pathway hears the Word and “does not understand it” (Matthew 13:19). The person in the good soil hears the Word and “understands it” (Matthew 13:23). Set these verses side by side, and the understanding that marks the good soil turns out to be the very thing Jesus has described as a gift. The difference is not that one sinner was naturally more intelligent, humble, wise, or spiritually inclined than another. The difference is the sovereign grace of God.
The rest of Scripture speaks with the same voice. In Ezekiel 36:26, God promises to remove the heart of stone and give His people a heart of flesh. Notice who performs this work. God does. In John 3:3–8, Jesus teaches Nicodemus that no one can see or enter the kingdom of God apart from being born again, a sovereign work of the Holy Spirit. In John 6:44, Jesus explains that no one can come to Him unless the Father draws him. And in Acts 16:14, when Lydia heard Paul’s preaching, we are specifically told that the Lord opened her heart to pay attention to what Paul was saying. The Word was proclaimed outwardly, but God performed the necessary work inwardly. James 1:18 and 1 Peter 1:23 likewise connect the new birth with the Word of God. Peter speaks of seed as well. We have been born again, he says, “not of perishable seed but of imperishable,” through God’s living and lasting Word. Two verses later he calls this Word the good news that was preached (1 Peter 1:25). The seed in the sower’s hand is no ordinary seed. God uses the proclamation of His Word as the means through which He brings sinners to spiritual life. The Holy Spirit opens blind eyes, gives a new heart, and brings the sinner willingly to Christ in repentance and faith. The fourth soil is good because God has graciously made it so. What the parable shows us in the fruit, the rest of Scripture explains in the root.
What enormous encouragement this gives us in evangelism, and what a solemn warning concerning false professions of faith. We cannot regenerate anyone. We cannot manufacture saving faith through persuasive techniques, emotional manipulation, or human effort. As Paul wrote, “I planted, Apollos watered, but God gave the growth” (1 Corinthians 3:6). We preach Christ crucified and risen, calling all people to repent and believe, knowing that everyone who comes to Him will be received. In Luke’s account, Jesus presses the point home: “Take care then how you hear” (Luke 8:18). Our confidence must never rest merely upon a decision we once made, an emotional experience we once had, or the length of time we have been associated with a church. The question is whether we are presently trusting Christ and whether our faith is bearing the fruit that His grace produces. No Christian is without sin, and our fruit is never the ground of our acceptance before God. Christ alone is that ground. If this parable leaves you troubled, look hard at what you are relying on. Your own efforts cannot bear that weight, and neither can your faithfulness. Make sure your full reliance is on Christ Himself. The same sovereign grace that brings us to Christ keeps us in Christ (Philippians 1:6). And so we sow the gospel freely, examine ourselves honestly, rest in Christ completely, and give all the glory to God. Salvation, from beginning to end, is of the Lord.
