What does the Bible say about the Holy Spirit's coming?

According to John 16:8-15, the coming of the Holy Spirit is significant as He was sent by the exalted Christ to convict the world concerning sin, righteousness, and judgment. This event marked a pivotal shift in God's redemptive plan where the Holy Spirit would guide believers into all truth, revealing deeper insights about the nature of sin and the righteousness that is found in Christ alone. It is essential for Christians to understand that the Holy Spirit's work is both a comfort and a conviction, guiding them as they grow in faith and truth.
