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. The Holy Spirit sees everything that goes on in our hearts and in our minds. Nothing is hidden from Him. To understand this better, let’s talk about the 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 Saviour, 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 no 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 works in many ways. First, the Holy Spirit convicts us of our sin. John 16:8. He uses a mother’s prayers, or a tragic experience, or a pastor’s sermon, or some other experience to convict us of sin and of our need to give our lives to Jesus Christ. Without conviction, we could never have our sins forgiven, we could never be saved, and we could never go to Heaven. The Holy Spirit allows us to start a new life. The Bible says that we are dead in our sins (Ephesians 2:1). Our spirit within us, made in the image of God, is dead toward God. Mankind needs life. Yet, we have all sinned and, therefore, are dead toward God. The Holy Spirit, however, gives us new life in Jesus Christ. Jesus said, “No one can see the Kingdom of God unless they are born again” (John 3:3). The Holy Spirit is the one who makes you born again; it is a supernatural act. It is not the good things we have done, but God’s mercy through the Holy Spirit that saves us (Titus 3:5). All we have to do is accept the gift of salvation by accepting Christ. The Holy Spirit lives in us. As you read this, you may realise that you are spiritually dead, but God says, “I will put my Spirit in you. I will come to live in you.” That is the reason we should never take anything unclean into our bodies. That is the reason we should discipline our bodies. God loves your body. He does not want it polluted by fleshly lusts or harmful substances. The Bible says, “Don’t you know that you yourselves are God’s temple and that God’s Spirit dwells in your midst?” (1 Corinthians 3:16).
