My mom gave me some friendship bread from amish country. It is actually the better that you use over 10 days. You are also getting a set of directions in order to make the bread precisely right. When it is complete you will have an additional 5 other batters to give away to others.
You must follow the recipe or risk having too much. Too much will make you too fat. If you hoard the bread, you will be over run. It is the same thing with God's word. If you try to keep it to yourself it will be too much you will become too fat and unable to work.
Also, if you alter the ingredients you will come up with a different product entirely after a while. This is the same with God's word. If you alter it instead of using it in context as God's word describes you will have different results.
