bread and fish again?

Matthew 15:29-39

The key words are: amazed, compassion, satisfied. I'm sure there is something significant about the disciples having seven loaves, as opposed to the five loaves in the previous miraculous feeding, and there being seven baskets of left overs, as opposed to the twelve in the previous feeding.
I wonder if this ever got old for the disciples. I wonder is they stopped being amazed by what Jesus was doing because they had seen it so many times. I can almost pick it up in their response to Jesus; "Hmmm, I wonder where we could ever find enough bread to feed this many people... Jesus? Here's seven loaves. Do your thing." I prefer to see it that way because otherwise the disciples are just thick. Can't they remember the time that Jesus fed 5000 with a boy's lunch?
Before I am too quick to judge, I must examine my own life. There have been countless times where I have seen the work of God and yet, in a similar circumstance, I stress, worry, plan, etc. and forget to simply have faith in the work of Jesus. How difficult is it to admit that I'm in over my head, there's nothing I can do and I am trusting fully in Jesus to do something? My track record says it is pretty difficult.
