Naaman lost his temper. He turned on his heel saying, "I thought he'd personally come out and meet me, call on the name of God, wave his hand over the diseased spot, and get rid of the disease." 2 Kings 5:11 (MSG)
My wife and I sat in the living room last night talking about the way you picture your life turning out, and the way it actually ends up looking. From the time we're little children we are asked "What are you going to be when you grow up?" Without being aware that we're doing it, we begin to plot, plan and prescribe the path we want our lives to take. Somewhere along the growth curve we become aware of God's presence on the journey. Instead of relinquishing the Google map we printed in on our heart and brain of the path we're taking, we ascribe authorship of the map it to God. We mentally stamp God's approval on it. Sometimes we even get so bold as to proclaim it: "God called me to…," "God wants me to…," "God is leading me to…,"
Like Naaman, we want God to work the way we've imagined and prescribed He will. We want Him to lead us where we want to go. Then we kick and scream at every detour, or like Namaan we simply opt out and head off on our own (then find out He planned for that, too, dangit).
God cannot be confined except within boundary lines that He, Himself, has set. He certainly cannot be confined by an individual human's thoughts and desires. His plans and designs for us are infinitely more intricate and complex than we can possibly fathom. We can chart a course, but we shouldn't be surprised when the journey takes us on a much different path than the one we imagined.
"In his heart a man plans his course, but the LORD determines his steps." Proverbs 16:9 (NIV)
