The Parable of the Householder concludes the series in Matthew 13 by illustrating the responsibility of scribes instructed concerning the Kingdom of Heaven. Jesus explains that every such scribe who has been trained for the Kingdom is like a master of a house who brings out of his treasure things new and old. The householder represents the true minister who feeds the household of faith from a rich, inspired storehouse of spiritual treasures. A scribe functions as one trained and skilled in God's Word, much like Ezra, who reads and expounds the law so that people understand it and live accordingly. In the same way, a minister dedicates himself to studying Scripture in order to expound and illustrate its laws, statutes, and principles for the benefit of others. The term translated "instructed" indicates that the scribe is a disciple who continues to learn while teaching, following the pattern Jesus established when He sent out His disciples to preach after instructing them. The minister therefore serves simultaneously as student, teacher, and leader. As householder, or master of the house, he exercises authority and bears final responsibility for what is best for the household. This role carries the commission to preach the gospel, equip the saints, and help bring people to the measure of the stature of Christ. The treasure from which he draws is a storehouse containing all that he has learned and experienced in God's truth and way of life. From this store he supplies what is needed, carefully balancing the old with the new so that neither is neglected. In practice this means teaching from both the Old and the New Testaments without discarding what is old, just as Jesus Himself took established understanding of the Kingdom and shed new light upon it. Having received instruction and sufficient understanding, ministers are to use these resources to enrich their spiritual families and reflect the knowledge they have gained to fellow members of the church.

Teaching forms an indispensable element of God's present activity under the New Covenant. The church's work is fundamentally educational, with teachers ranked third in order after apostles and prophets. The noun teacher appears sixteen times, the noun teaching twenty-four times, the verb teach thirty-nine times, and related terms for instruction eighteen times across the New Testament books written after the New Covenant's establishment. This frequency underscores teaching's centrality rather than any indication that the New Covenant remains future. Christ's explicit directive to make disciples of all nations and to teach them everything He commanded confirms that instructional activity continues until the end of the age. The role of teachers aligns directly with the New Covenant's gradual, individual implementation. Because God ratifies this covenant person by person rather than with an entire nation at once, some individuals stand under its terms while others do not. During this extended period, those already called require instruction so they may observe all that Christ commanded. Teaching therefore serves the incremental process by which names are added one by one to the Book of Life. Only when that process concludes, when no further individuals remain to be called, will the need for such teaching cease, as all who have accepted the covenant will then know the Lord without intermediary instruction. Until that termination, teachers fulfill an essential function within the ongoing realization of the New Covenant.

The role of teachers centers on the repeated commission to feed Christ's sheep, a responsibility given first to Peter and extended to all under-shepherds. Christ owns the flock by creation and by redemption through His blood, so teachers serve only as under-shepherds accountable to the Chief Shepherd. Their primary duty is to feed the sheep by teaching and communicating the Word of God through regular, orderly, comprehensive, balanced, prayerful, and obedient instruction rather than random or selective comments. This task belongs especially to ministers, whose chief function is to teach Scripture by word and example, yet it also rests on parents toward their children and on other leaders and mature members in lesser measure. Teaching must proceed from conviction that every part of the Bible is God's Word, not mere preference, and must be preceded by prayer that opens hearts to what God is saying so that lives are changed and others are taught effectively. The same commission connects directly to the repeated invitation to follow Christ, which requires self-denial and daily taking up the cross. Teachers therefore model discipleship by renouncing sin and anything contrary to God's will, keeping their eyes fixed on Christ as the standard so that service remains humble, unified, and free from self-reliance or judgment of others. In this way the work of feeding the sheep continues Christ's own ministry through the church until His return.
