Soggy:How do you know that it was the biblical God that called you and not Zeus or Buddha?
Because he signed the letter of course. LOL...just kidding.
I suppose I believe it was that God of the Bible because the Bible was at the heart of what I was drawn to.
While we're here I want to try to answer fndmylove's question.
I never understood the phrase "god has called upon me" or "god has called me" or "god asked of me" ... what does this mean exactly? For you specifically, did you hear voices in your head? Did you have some event that you associated with god calling you? What was it exactly? The reason I ask is that I have had some particularly unbelievable events happen to me in my lifetime and I have found no way to explain (with science or logic) the origin or behavior of these events. I often wonder if others have had simalar events, and subsequently associated them with the supernatural. I do associate them with something I don't understand, but I cannot assume anything in particular.
For me...no voices, no buring bush, no physically unexplainable events. I was fine, great wife, great kids, plenty of money (not any more but oh well) and plenty of new challenges and excitment. I was happy and if there was anything missing, I didn't know about it...until I just started feeling like I had somehow missed something, had somehow failed to do something important. More specifically that I had failed to do something important for my family. I didn't know what it was that I had failed to do. Everyone was healthy and reasonably happy and we lived in an ok house on 4 acres with pets all over the place (including a couple of horses) and a garage full of fishing tackle and dive gear. It wasn't very long before I knew what it was that I had missed and what it was that I had failed to do. I had neglected to get to know God and I hadn't seen to it that my family knew God.
To make the rest of the long story short, with prayer, reading the Bible and listening to the Bible taught, it was just one revelation after the other. God will do things to grow faith and those things are powerful convincers.
