dothack- I have ocd- technically, though I barely feel it's presence anymore. In what way do you mean that it interferes with God's word? I'd like to give advise, if I can, if my experience might help. I'm saying a lot here, and some of it is less related to the topic, because I'm not sure if any part of it can help. For me, I used to check everything, and i'd have repeating thoughts (often, prayers) that would annoy me.
In regards to the checking, there was always the "what if," and I had to do everything 3 times to make sure things were safe. But God is my strength. If the "what if even though I locked the door, it's not really locked?" starts, I ignore it because I know that even if the door isn't locked, God can protect me, and if something happens to me, I'm still in God's hands, and not a prisoner of fear. I kind-of decided one day, that fear was my biggest fear, and that has helped me- even way beyond the OCD, to go after my dreams.
In regards to the repeating prayers, I let it gain so much control when I didn't know what was going on, and because prayer for others isn't bad, I couldn't trust that to push it away was okay; I was afraid it might mean I was pushing away God, or failing to help others. But then I realized that God is in control whether I pray or not, that He understands what I'm dealing with, and that he isn't the author of such slavery. I understood that he was freeing me to the point where if I stopped praying for others completely for a time, it would not result in their demise. God could always put it on someone else's heart to pray, or God could help without prayer. And over time, that is mostly gone- it may start-up a bit when I'm stressed-out, but I push it away fast, and trust God to help, and it subsides.
If you have a thought, and it's not repetitive in nature, I don't think it's OCD, but whatever is telling you that you can't trust the idea because of OCD may be your fear of it, or may be satan's way of making you insecure. If what you think might be God seems to be backed by scripture, then it really might be God. Look at whether it seems like sound advise. That way, whether it is him or not, if it is sound, it is good. You can tell him, "I'm not sure if it's you. I think it is, so I'm acting upon it. But if I'm wrong, I'm still listening. Let me know." Like the story of Baalaam (I think), where God blocked him by stopping his donkey, and then sending an angel to block his path, God can interfere if you make the wrong choice. OCD and other anxiety disorders can paralyze a person, but we have to move in life. We must trust that God can interfere if we hear him wrong. So if I am asking Him what to do in life or some other non-Biblical question, and I get an answer, but am not sure whether it's him, or not, I ask him, and trust him to interfere if need-be. Even here, I don't like the idea of so many people who don't know me reading this, and assuming I'm weird (people who do know me may think I'm weird, but in a good way). But I think it can help, and God can always prevent it from being sent, or add/delete a line, or whatever if he chooses. So I'm doing what I prayerfully think is good, and trusting with the rest.
As far as wanting a real relationship with him, keep praying, keep reading his word (seek out verses that point to God's faithfulness and power to be there for you, and in your prayers, mention the pieces of scripture that reassure you, ie: "i know you did this for/ said this to ____, this is what I'm asking from you"), keep noticing the beauty and wonder of God's creation, keep thanking him, and keep asking him for a close relationship, and it WILL come. It did with me; I'm not sure when I lost that relationship, or when it came back, or if it really ever was gone- though I was sure at the time, that it was, so it must have been. But I knew from scripture, that God hadn't left. It was just the loss of that feeling of closeness. But it is back. Maybe God was testing my dedication. Maybe I was wrong all along. I don't know. But if you stay true, it will come, and you will be stronger for it.
for your heavenly Father knoweth that ye have need of all these things. 33 But seek ye FIRST the kingdom of God, and His righteousness; and all these things shall be added unto you. 34. Take therefore no thought for the morrow; for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
