Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty. (2 Corinthians 3:17)
It is essential that believers understand the importance of the Holy Spirit in God's redemptive process, and His work in the lives of individuals and the church as a whole. Sadly, many Christians have no concept of the Holy Spirit's work, especially in the days of the Old Testament. Without the Holy Spirit, there would be no creation nor human race. Without the Holy Spirit, there would be no Bible, nor power and boldness to proclaim the gospel. Without the Holy Spirit, there would be no faith, no holiness, no new birth or regeneration - in fact, not one person would ever be saved.
The Holy Spirit is often referred to as "it." He has been called "jargon" or a "theologically scary church phrase" which Christians should not mention when witnessing. But the Holy Spirit is not an "it" or "jargon". He is a divine Person, a part of the Trinity, the third person in the godhead, and He is active and alive in the hearts and lives of believers today.
