The Holy Spirit

  Last night I got to go to Angel's bible study with her, and it was a lot of fun. It was really cool to see young married couples come together in fellowship and spend time taking a deeper look into God's word. One of the topics we got talking about though was the Holy Spirit. It was more towards the end though, so we didn't get a long chance to discuss it. Anyway, the dude who led, Mike, was saying how lots of things changed in our relationships with God after Jesus. Such as now we no longer have to make sacrifices to God for our sins because Jesus is our sacrifice. There are no longer walls between God and us like there were with the temples and the holy of holies and all that kind of stuff. Mike also mentioned that now the Holy Spirit is more active too because of Jesus. In the old Testament you only saw the Holy Spirit when miracles were performed. It often says "and the Spirit of God fell upon them and such and such happened". But now the Holy Spirit is continually with us and active inside us.

Well, that got me thinking, and I disagree. First off because you do see cases when the Holy Spirit is living in someone and doesn't just 'come down' for a time. Like when David is anointed king it says, "And the Spirit of the Lord rushed upon David from that day forward." So the Spirit was continually with him. And you can find several other passages that are similar to that. So obviously the Spirit of God, or the Holy Spirit was very present in the Old Testament. But I can also understand where Mike was coming from when he said that, because in Acts you do read a lot "and they were filled with the Holy Spirit." And you do see much more of the Holy Spirit in the New Testament then in the Old. But here's something else I thought. In the Old Testament it was God. They thought God was just God. I don't think, and I can't find  anywhere, where they mention the Trinity in the Old Testament. The people didn't even know of Jesus because he hadn't come yet. But did that mean that Jesus didn't exist? No! he very much did! So maybe they didn't really understand that the 'spirit of God' was the Holy Spirit. 

Blah... I don't know how well I'm getting my point across, and I know I'm saying this a lot out of ignorance and more based on my own thoughts and feeling then on Scripture. But I guess what I'm trying to ask you guys is what do you think? Do you think that the Holy Spirit became more active after Jesus' death and resurrection? or do you think he's always been just as present? I guess what my point is, is that God never changes. We know that. I think that as time goes on God reveals himself more and more to his people. So to the people in the OT, they didn't fully understand the Trinity, or didn't even know that God IS three in one. Don't get me wrong, I'm not saying that now we do fully understand the Trinity. Far from it! But because we already have a foundational truths from all the generations of Christ followers before us, we're beginning to know God more and more. 

So, I need your help! I'm totally going to be searching God's word for more answers, but any thoughts, or questions, or whatever from you all would be awesome! Hope my thoughts came across as some what clear...
