The sermon focuses on the Great Commission in Matthew 28:16-20, defining what a disciple is and explaining how disciples are made, with a strong emphasis on the role of the local church. The main points are: • Jesus Possesses All Authority: The command to make disciples is grounded in Jesus' declaration that "All authority has been given to me in heaven and on earth." This authority is absolute, granted by the Father, and rooted in His divine nature. While not yet fully recognized by the world, it is the real and ultimate authority under which the church operates. • The Central Command is to Make Disciples: The sermon corrects a common misinterpretation, emphasizing that the primary verb is not "go," but "make disciples." The command is better understood as, "As you are going, make disciples," meaning disciple-making is a continuous purpose to be carried out wherever a believer is. • The Nature of a Disciple: A disciple is defined as a person saved by God's grace alone, through faith alone, in Christ alone. This involves recognizing one's sinfulness and trusting in Christ's finished work. Disciples are not perfect but are characterized by a wholehearted commitment to following Jesus' commands, which are based on God's moral law. They are sensitive to their sin and actively seek repentance and growth. • The Method of Disciple-Making: The primary method for making disciples is the preaching of the Gospel. This leads to the formation of churches, which are the visible expression of God's kingdom on earth. • The Role of Baptism and the Church: Baptism is presented as the authoritative sign of the New Covenant and a crucial part of making disciples.
