How big is your God?

Today was a long day (as Tuesdays usually are) for me at Bible College: three lectures, from 10am to 9pm. It was my third and final class that has inspired this particular post. It's an issue I've heard time and again, and here it is, in blog format.
How big is your God? Not in the sense of some graven image or 'idol', but in the sense of your own faith in Jesus. If you are a Christian, how big is your God? Now most will answer with a resounding "BIG", which is cool. But isn't it interesting that a lot of Christians don't believe in half the miraculous wonders that are found in the Bible? For example, in my last class of the evening, we touched briefly on the Book of Jonah. You know the story:
- A guy is called to preach to Nineveh
- He runs off in the opposite direction
- He gets caught in a storm
- He gets eaten by a giant fish, and then gets spewed on dry land three days later.
- God calls him again; this time the aforementioned guy agrees, goes to Nineveh.
Most people have a problem with the content of this book. How can a guy get eaten by a fish? How can the guy survive in there? And what's with that fast-growing bush? That doesn't happen in my garden.
You get the idea...miracle after miracle is found in the Book of Jonah. But why is it so difficult to accept that God can do the stuff he did with Jonah? Is this not the same God who created the Universe? If God can create our entire Universe (which we believe), work signs and wonders through Jesus (which we believe), as well as a chosen few following Jesus' life (which we also believe), then why can we not stomach Jonah? Granted, we don't hear a lot of stories about people living in fish stomachs. But that's not to say that God cannot do it. He did it with Jonah, after all. And he did some pretty amazing things through Moses - the parting of the Red Sea comes to mind.
So I ask you again: How big is your God? When you read your Bible, do you meet with an omnipotent, omniscient, omnipresent God who wants to know you? Or do you meet with the God that you stuff in your pocket, because he "fits well" with your ideas?
Let us remember in prayer and faith that God is far bigger than any of us, and anything less is to reduce God to a mere idol.
Let's not make that mistake. Just because we seldom see the miraculous, doesn't mean to say that it doesn't happen.
