Slavery for a reason

Tonight after dinner we sang Psalm 105 which you may recall sings of the wonders of God through the plagues and the freeing of the Israelites from slavery. I began to think about how wonderful it must have felt for those people who had prayed and prayed for deliverance from their slavery and were finally blessed with freedom. How thankful and joyful they probably were. I realized that these people were probably at times extremely frustrated at their condition - to say the least. They cried out to God for their freedom and they probably wondered what was God's purpose in keeping them in their bondage. What possible reason did God have for enslaving them to this Godless Pharoah who was often times cruel. We have the benefit and luxury of hindsight which the Israelites did not. We can now see the providence of God through their plight and the glory of the whole ordeal. It makes me realize how many times I wonder why God is doing something to or with me, and I'm encouraged to perserve in my faith because of what happened in Egypt so long ago. Maybe, just maybe, God would have me go through a trial for the encouragement of another of His children six thousand years from now. I can rest in the promise that everything is for my good, but surely, even if it is just for the benefit of a saint generations down the line who is sitting at her dinner table surrounded by children and not understanding at the moment the full benefit of her many "blessings" (who have just completely littered the floor with food for the third time in a day :) ) then surely it is a good thing, eh?
