From my point of view, some of these choices (like jobs, collages, majors, cars, classes, when, and where) seem so pivotal. I feel like the whole future of my life depends on my decision.
Fortunately, God has a different view. He sees reality, the way things really are. The reality is, God has a plan for my life... even to the end. Because He's sovereign, God has my life under control. My choices won't be a surprise to Him.
I know this is true, but in the midst of life's craziness it's often hard to believe. Sometimes, I start believing the lie that I actually plan my life. Although I do have choices, and although my choices do effect my life, I'm not the one who directs it. I'm tired of worrying over the future, so I'm giving it over to the One who has it in His hands anyway. I will seek Him for every decision, and I will trust Him.
God delights in being trusted. Want to make God smile? Then trust Him. Trust Him with everything. Trust Him with your life. I can't see the road ahead and I still don't know what all of my decisions will be. But I'll leave the answer to God. After all, He's written all of history - I'm sure He can write my life.
A man's heart plans his way, but the Lord directs his steps.
