I think this should be a 4 letter word. Really, why do we need it. It just gets in there and messes everything up. For most of us I think it is very hard to live without. It takes effort. That is where faith comes in. I think it is easy to live without doubt if you have faith. Without faith, I think you are left to your own devices and unless you think you are the best thing since sliced bread you are going to doubt - your choices, your achievements, your abilities.
I am so grateful to have faith. Without God I would be a disaster. I would be doubting everything - questioning everything. If I thought I had to fight this cancer on my own I would always wonder if I was strong enough to do it. Instead, I KNOW it is in God's hands - I also KNOW that He will take incredible care of me. I have no doubt that there are a whole bunch of poor dead cancer cells in my body that will soon be on some pathologist table wishing they hadn't messed with me and my posse.
