I’m sure it’s a point I’ve made before, but I see it all the time.  You can even find lists of God’s promises cherry picked from throughout the scripture without regard to context.  Certainly God is good.  I don’t think it’s out of line to lay clame to a statement like the one in this passage if one is a child of God, but we can point to scripture that really does say that to us.  We don’t need to go shoplifting.  That said, we will not find anywhere in scripture that says we will be spared all suffering.
