Sometimes talking about trusting God and ACTUALLY trusting God are two totally different things. It's easier when it's all academic. It's hard when the rubber actually meets the road.
We like it better when things are easy and you can see how it's all going to work out. It makes sense. It's logical and ascertainable. Unfortunately, life is rarely like that. Surprises happen, and sometimes they're not happy ones. Stuff happens that we don't expect and screws up our plans. BUT...
We have to remember that even though we were caught unawares, God was not. He knows the end from the beginning and he knows not only what will happen but how he's going to get us on the other side, wiser than we were before we started.
This faith thing is always worth it, but sometimes it's not all that easy.
