The soils in the Parable of the Sower represent the different conditions of the hearts that receive God's Word, and the parable's focus falls on them more than on the sower. Hard ground, like a packed road, is a heart calloused by sin; the seed makes no impression, Satan steals it, and the hearer returns to the ways of the world. Stony ground is a shallow heart that is excited by the gospel's novelty and feels temporary peace and happiness, yet has no repentance, no real sense of sin, and no appreciation for Christ's sacrifice. With no root of personal conviction, it withers under trial and persecution, because mere human emotion cannot sustain the long process of conversion. Thorny ground is a heart crowded by the cares of physical life and the deceitful enticements of wealth, which distract from God and Christian growth. Wealth promises happiness but never delivers it, and it tempts people toward dishonesty and oppression. Good ground is a rich, fine soil: a mind softened by God's calling that submits to the full influence of His truth. It accepts the Word, lives by it, and bears fruit thirty, sixty, or a hundredfold. Since three of the four soils yield no fruit, each person must ask honestly how much spiritual fruit he is producing.

The four soils in the Parable of the Sower stand for the different responses people give to the gospel of the Kingdom, while the seed is God's Word. Hard, unturned ground is the heart calloused by sin; the Word makes no impression, Satan snatches it away like birds taking seed from a road, and such people drift back into the ways of the world. Stony ground has too little depth for roots. Those it represents are excited by the offer of mercy, pardon, and peace, and they grow quickly, but they have no real appreciation of Christ's sacrifice and show no true repentance. When the sun grows hot, whether through the exposing light of God's truth or through trial and persecution, they wither, because emotion cannot sustain them through the long process of conversion. Thorny ground is the heart crowded by the anxieties of daily life and the deceitfulness of wealth. These distract Christians from God and spiritual growth. Wealth promises happiness but leaves them spiritually empty and produces bad fruit such as dishonesty and oppression. Good ground is the mind softened by God's calling, genuinely receiving the Word and submitting fully to the influence of His truth. Like rich soil, it yields a crop of thirty, sixty, or a hundredfold, bearing much fruit.

In the Parable of the Sower, the seed is the word of God, and the soil represents four kinds of hearers. Along the path, the devil snatches the word away before people believe. On the rock, people receive the word with joy but have no root, so they lack real commitment and fall away when testing comes, such as the test of keeping the Sabbath. Among the thorns, people hear, but worries, riches, and the pleasures of life choke them, and their fruit never matures. This third soil is the most concerning, because it shows people who may have borne some fruit yet stopped growing and abiding in Christ. Good soil is the heart that, after hearing the word, clings to it with an honest and good heart and bears fruit with steadfast endurance (hupomone), holding on under pressure and trial. For this reason Christ commands, "Take heed how you hear."

In the Parable of the Sower, the different grounds represent the varied responses of Israel's citizens to the word of the kingdom. Three of the four soils produce nothing of value: the wayside, the stony places with no depth of earth, and the thorny ground. Only the good soil, the one who hears the word and understands it, bears fruit, yielding a hundredfold, sixty, or thirty. All the soils receive the seed, but God prepares only some of them. The critical factor is whether God has given the hearers the means to respond properly. The masses had shallow interest and even a willingness to repent and be baptized, but without depth because their hearts were far from their King. They claimed Abraham as father yet lacked ears to hear, and they sought a messiah who would improve their politics while leaving their religion and morals unchallenged. Their dull hearts fulfilled Isaiah 6:9-10, so they were living proof of the parable. By contrast, Jesus had prepared His disciples to hear and respond, and they were the good soil that would yield an increase. Read in its context of rebuke to the nation, the parable shows that fruitfulness depends on a heart God has prepared to receive His word.
