What is clean?

Here is Environmental Working Group's shoppers' guide to pesticides in produce.

This list is certainly helpful to make good choices on a tight grocery budget, but I find of great comfort the first words that eating fruits and vegs far outweigh the risks of exposure to pesticides. With that in mind, don't eat in doubt, meaning God has given us wisdom to make the best choices for our children, but He has also made ALL things clean. Therefore we are not to live in fear, but to live victoriously as those set free from the yoke of slavery to sin! Sin still rules this world, and we are therefore still subject to its effects, but our hearts can be set free. Let this be a reminder, as it is to me, that the hearts of our children are of utmost importance. Directing them in the ways of God must rule over the health of their bodies, their education, their activities, etc. Be blessed by the Truth that sets us free from ourselves!
