Throughout my life, I'd hear about this guy called the Holy Spirit. Now, I'm not gonna lie, I didn't know Him or even about Him til recently, and I'm still learning. So just like me, you're thinking "who's this guy buv?" Ite lemme break it down.
The Holy Spirit is part of the Holy Trinity of God. He is the presence of God, He is most definitely a real person and He deserves to be treated like one. He has emotions, intellect and will. The Holy Spirit has always been about, He just changed the way He moves. For example, in the Old Testament times he came upon people to empower them for a service (Judges 3:10, 6:34, 13:25, 14:6, 1 Samuel 10:10), but the New Testament says He indwells within us to take up permanent residence in the body of a believer (1 Corinthians 3:16, 2 Timothy 1:14, Romans 8:11).
So you're here thinking "rahh so how and when did this indwelling happen?" Ite so boom, Jesus and John the Baptist both prophesied that the Holy Spirit was en route (Matthew 3:11, Acts 1:5). Ten days after Jesus prophesy in Acts 1:5, the Day of Pentecost happened. In Acts 2, after Jesus ascended to heaven, Jesus' followers gathered together for the Feast of Harvest (aka Pentecost) and the Holy Spirit filled the house where they were sitting and they started to speak in tongues. People thought they were drunk but Peter stood up and preached about repentance and the gospel of Christ and by the end of the day 3,000 people became Christians. So basically now, when you give your life to Christ, at that very moment the Holy Spirit dwells in you from then on and forevermore.
Ite so this is starting to add up yh? Okay. So..."what does the Holy Spirit do?" You may ask. The Holy Spirit is always on job, never lacking. The Holy Spirit does more than me or you could ever imagine, so imma just give you a taster. He is our Helper (John 14:26), He guarantees our salvation (Ephesians 1:13, 4:30), He assists you in prayer (Jude 1:20), He intercedes for us (Romans 8:26-27), He regenerates and renews believers (Titus 3:5), He baptizes believers into the Body of Christ (Romans 6:3), He gives new birth through His power (John 3:5-8)...continued in comments - 2 hours ago
