She had just had four teeth pulled out.
And yet, as we pulled into the road that would take her home, she carried on conversation as if it was no big deal that blood was pooling in the holes her teeth once filled.
We were part way through a discussion of how many needles she had been given to numb the pain, when it occurred to me. How could she talk if she could not feel her mouth?

Have you ever asked someone how they got through a particularly difficult time, and gotten a similar reply?

It may have been literally impossible to get up and walk out the door, and yet somehow they got up and walked out that door. They may not have been able to fathom how they could possibly go back to work, and yet somehow they went back to work. And just like that, the impossible became possible.
Humans have been doing the impossible since the word was invented. So why do we find it such a wonder that the God of the universe would ask us to believe in him when he says he can do it!
Maybe it is because most of the time He chooses to work through us. And when all of our senses tell us we cannot do what we have been asked to, our feelings aren't an easy hurdle to jump.
Walking on water really just comes down to a step – a step that just happens to be on top of an ocean. It is not for us to decide whether the water will hold us. Our job is to step out on it.
