Isaiah 55:8 in the ESV reads "For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord."
What an amazing verse to keep in mind in the midst of struggles. When our lives don't go according to our plans, keep this verse in mind. First of all, for Christians, "our" life isn't "ours" at all. It belongs to God. That's what it means to surrender completely to Him. To hand God the reigns and say "Okay, Lord, where do You want to go? What do You want to do?"
Secondly, there's also a problem with the other "our" in that sentence. We shouldn't be making our own plans! That's not our job; it's for God to do. I can tell you from plenty of experience that "our" plans mean NOTHING to God. He wildly shakes them up all the time.
"It's a funny thing, how much time we spend planning our lives. We so convince ourselves of what we want to do, that sometimes we don't see what we're meant to do."
-Susan Gregg Gilmore
Humans make plans and think that anything other than those plans are failure. This isn't true! Rather, whatever God leads you to do is what you should do, whether it follows your plans or not. Oftentimes, this trust is incredibly difficult to give. In fact, I myself love to plan. It helps me stay focused and have goals. I'm not saying that all planning is wrong—it just has to be aligned with God's plans for you, and if He decides to change them, then submit. Everything is harder if you don't submit to Him and His plans.
Even if it doesn't seem like it, God's plans are always far superior to our own. He knows the future; He knows what is best for us; He loves us. The God who made the universe, who made you, who made everything knows the number of hairs on your head—He can take care of you. (Luke 12:7) When our plans seem like the best way to go, remember Isaiah 55:8. God's thoughts aren't the same as ours, and we don't know His plans for us or others. No matter your circumstance, I promise you that God is with you. He'll never leave you and He does indeed have a plan for you, even when it doesn't seem clear or like the best route. Trust Him in all things, and let His plans guide you.
Update on my friend who was in the accident last Wednesday: Her surgery on Thursday went about as well as the doctors had hoped. Though she still has no feeling in her lower extremities, she does have feeling one inch lower than she did the previous day. She starts therapy soon and will be transferred to a hospital that specializes in spinal chord injuries. Keep praying for a miracle; it already is one that she is alive and has no apparent brain injuries! Thank you for your faithful prayers!
