Why Eli Has Allergies

I had to go through McDonald's drive-thru to get food for Eli before we met family at the restaurant. If you haven't figured out by now, Elijah has numerous allergies (dairy, egg, peanut, tree nut, cats, dogs, dust mites, mildew, penicillin, etc.). We have to be very diligent to make sure he doesn't get a hold of anything that will make him sick. We carry benadryl and an epi-pin with us in his backpack everywhere he goes. And we try to make sure that he has "yummy" food to eat, too, when he can't have what everyone else is eating. Hence the reason for the happy meal - plain hamburger, apple dippers without the dip, no fries and a Hi-C. And hopefully nothing in the bag has come in contact with any cheese in McD.'s kitchen!
At the "real" restaurant, my brother (who recently found out he's allergic to shellfish) asked, "I can understand why I have my allergy because God told the Israelites not to eat shellfish in the Bible, but why would God make someone allergic to food that He says is good to eat?" An excellent question which I didn't get to answer. So here's what I think... Back at creation, God made Adam and Eve's bodies perfect. No sickness, no bad germs, no defections, no genetic weakness. But when Adam and Eve sinned - evil, corruption, and death entered the world. Life was not perfect anymore. Now people started getting sick. And dying. Different illnesses and diseases started to affect people. This still happens today. (A hundred years ago, AIDS didn't exist.) Our immune systems became weaker. Our immune systems started to attack "good" stuff (like milk and eggs), not recognizing what it is. And people developed allergies. It's a direct cause of "the fall". God is Sovereign. But He has allowed this to happen because humanity has chosen sin. Even the innocent babies are affected...like Elijah when we realized he had food allergies. Even though at that point, he personally had not chosen to sin yet, his genes come from a line of sinners. And he was born with an imperfect body. Just like all of us. And although God has allowed this to happen, I also believe that God has a special plan for Elijah's life - a plan that somehow involves Eli's allergies. I'm not God, I don't know His plan, but I trust God in all. And I know that one day, I will have a perfect body. And if Elijah puts his trust in Jesus, he will have a perfect body, too; and he will be able to eat anything he wants to from the marriage supper of the Lamb.
