God's work is deeply tied to the cycles of planting and harvesting, reflecting the natural seasons He has established. He plants seeds of belief and spiritual truth, imparting understanding to empower those who receive it to succeed in the same process that Jesus Christ completed. This process reveals what crop God seeks to harvest: children in His image. Just as a farmer prepares the soil, God disturbs and turns over hearts so the seed of truth can take root. He scatters this seed through His human servants, waters it with the Holy Spirit, and tends to its growth personally alongside His ordained helpers. The church plays a vital role in this, promoting belief and providing a conducive environment for the seed to mature through preaching truth. Thus, God's purpose unfolds in nurturing belief in His firstborn Son and in the spiritual birth process, aiming to gather sons who resemble Him in character.

In the exploration of the parables in Matthew 13, the symbol of the seed emerges as a profound representation of God's sons. Within the Parable of the Wheat and the Tares, Jesus Christ clarifies that the good seed signifies the sons of the kingdom. This imagery aligns with the broader understanding of a seed as the means by which a plant reproduces and expands its domain. Just as a seed is the product and the vehicle of growth for a plant, so too are the sons of the kingdom the means by which the realm of God grows and spreads throughout the earth. These members of God's church are the initial kernels, the small beginnings through which His dominion is extended. In the Parable of the Mustard Seed, the seed further illustrates this concept, representing the church itself—small, weak, and few in number. Despite its humble start, akin to the least of all seeds, it is sown by the Sower, who is Jesus Christ, into the field of the world. The mustard seed's smallness underscores the church's modest origins, yet it holds the potential for expansion under God's design. However, the parable reveals a distortion when the mustard plant unnaturally transforms into a tree, exceeding its intended limits. This abnormal growth signifies the church's deviation from God's plan, becoming a place where negative forces, symbolized by the birds of the air, find a home. Thus, the seed as a symbol of God's sons carries both the promise of growth and the warning against straying from His intended path.

In the Parable of the Wheat and the Tares, Jesus develops the imagery of seed to reveal the identity and destiny of God's Sons within a world where good and evil are intermingled. Two sowers appear in the parable: the Son of Man, who is the owner of the field and sows only good seed, and His enemy, the diabolos, who secretly sows tares among the wheat under cover of darkness. The good seed represents the sons of the kingdom—those who have received, understood, and obeyed the word of the kingdom, becoming baptized members of God's church in whom the Holy Spirit dwells. Unlike the Parable of the Sower, where the seed itself represents the word of the kingdom, in this parable the good seed is the product of that word fully received and lived out, resulting in righteousness through walking worthy of God and becoming true children of the kingdom. The tares, by contrast, are sown by Satan among the wheat, not to be distinguished easily but to grow alongside the righteous, causing confusion and problems within the church. These tares are called sons of the wicked one, resembling true Christians in outward religious practice—attending church, praying, and reading the Bible—yet remaining unconverted religious hobbyists who develop character under Satan's influence rather than being originally created evil. This mixture demonstrates that the church of God on earth would be imperfect, containing both genuine, Spirit-indwelt saints with personal defects and unconverted individuals who associate with God's people without true conversion. The purpose of this seed symbolism extends to the process of training and testing the sons of the kingdom. God has sown His redeemed ones, represented by the good seed, into this world of sin and misery so that they may become true witnesses for Him in preparation for His coming Kingdom. Jesus' warning to Peter—that he was wheat to be sifted by Satan—illustrates that even the genuine seed faces trials and testing designed to refine character. This calls all of God's saints to watchfulness and prayer, guarding the field of their hearts against the enemy's attempts to sow tares within them. Ultimately, the separation between the good seed and the bad seed will only occur when the wheat has matured, at the harvest, when God will root out the tares and gather the righteous into His Kingdom. Until then, the sons of the kingdom are expected to bear fruit in the corner of the world where God has placed them, living as new creations bought with a price, indwelt by God's Spirit, and heirs of His Family and eternal life.
