It is impossible to understand the Bible, Christian living, the structure of the church or our own relationship with God without understanding the Holy Spirit. The Holy Spirit is not an "it." The Holy Spirit is a person. The Bible says that He is not something. He is Someone. He is God.To understand this better, let's talk about Trinity. There are three persons in the Trinity-God the Father, God the Son and God the Holy Spirit. Christians do not worship multiple gods. God the Son, or Jesus Christ, was God in human form. The Holy Spirit lives inside us when we accept Christ and helps us grow closer to God.The moment we receive Christ as Savior, the Holy Spirit comes to live in our hearts. The Bible teaches that the Holy Spirit is all-powerful and present everywhere. The Holy Spirit teaches us and takes us deeper into God's truth as we go along in our Christian life.There is not a person anywhere who can be a Christian without the Holy Spirit. There is not a person who can follow Christ without the help of the Holy Spirit. The Holy Spirit sees everything that goes on. He knows what goes on in our hearts. He knows what goes on in our minds. Nothing is hidden from Him."The Holy Spirit sees everything that goes on. He knows what goes on in our hearts. He knows what goes on in our minds. Nothing is hidden from Him." -Billy GrahamThe Holy Spirit is also called holy. The Bible says, "Be holy, because I am holy" (1 Peter 1:16). One of the Holy Spirit's ministries is to help make us holy-to become more like Christ.
