This article addresses Christian discipleship and the biblical Trinity (Father, Son, and Holy Spirit), with emphasis on the work of the third Person. Using theological description and analytical investigation, and with the doctrine of the Trinity as a framework, it examines the concept of mathētēs and the ontological identity of the Trinity as set forth in the Great Commission in Matthew 28:19-20, then analyzes key elements found in Jesus’ teachings on discipleship. It highlights the Holy Spirit’s role in maintaining humanity’s connection with the triune God, which results in four essential aspects for the follower of Jesus: justification, sanctification, the endowment of charismatic missionary capacities (spiritual gifts), and missionary action in fulfilling the Son’s commission. Finally, it concludes—based on the analysis of Jesus’ evangelical commission— that all three Persons of the Trinity play a vital role in forming disciples for God’s kingdom, which establishes the connection between the divine Persons and the disciple, whose bond is promoted by the economic action of the Holy Spirit, who uses the disciple-making ministry to form other new disciples.
