Why is the coming of the Holy Spirit important for Christians?

The arrival of the Holy Spirit at Pentecost is crucial for Christians as it signifies the fulfillment of God's promises and initiates the last days of the Church's mission. The Spirit empowers believers to proclaim the gospel and confirms their identity as children of God. In this dispensation of grace, the Holy Spirit continues to work in the lives of believers, guiding, teaching, and applying the truth of the gospel. Without the Spirit, the mission and ministry of the Church would lack the divine strength necessary for salvation and sanctification.
