This study guide explains how the Holy Spirit serves as the essential provision for the Christian mission. It emphasizes that Jesus’ departure was actually advantageous for the disciples because it allowed for the arrival of the Spirit, who offers a presence more intimate than a physical companion. The message outlines three primary roles of the Spirit: convicting the world of sin, guiding believers into all truth through the scriptures, and glorifying Jesus Christ. It argues that the Spirit’s work ensures believers are never ill-equipped or lacking the necessary tools for their spiritual assignments. Ultimately, the text illustrates that the Spirit connects the Father’s authority to the believer's life, keeping the mission focused on the glory of God.
