The bible is full of contradictions, they say.
Ok: here's one. Moses and God spoke face to face but wasn't allowed to see God face, because if he did he would die.
Some people will no doubt see this as yet another reason to write the Bible off.
But for those of us who know God, it's the only sort of language we can use. We need words to describe a God who is present everywhere and revealing himself everywhere, yet who so often appears to be hidden. We need words to describe a God who is approachable yet scary. We need words to describe a God who sees our frailty, weakness and sin and tells us that this is the place we can be strong. We need words to describe a God who has great power, yet whose power is shown in his Son being crucified. 
In the end, there are no words. They run out long before we can make sense of God. 
​I want to see God face to face. I believe I can. But then, maybe not too close ....

Just suppose, Moses hadn't gone over to the burning bush. What would have happened?
Silly question - we don't know. Nobody knows what might have been.
Yet I can't help thinking that God engineered things to persuade him to come over. God revealed himself indirectly and waited for Moses to make the next move.
I think this happens quite a lot. God makes the first move and waits for us to make the second one. I see a lot of that in the Bible.
So let's try and keep our eyes open. Maybe God will make a first move for us, that we really don't want to miss.
