Submitting self to God is the only real freedom-because the deepest slavery is self-dependence, self-reliance. When you live your life believing that everything (family, finances, relationships, career) depends primarily on you, you're enslaved to your strengths and weaknesses. You're trying to be your own savior. Freedom comes when we start trusting in God's abilities and wisdom instead of our own. Real life begins when we transfer our trust from our own efforts to the efforts of Christ.
When I was 25, I believed I could change the world. At 41, I have come to the realization that I cannot change my wife, my church, or my kids, to say nothing of the world. Try as I might, I have not been able to manufacture outcomes the way I thought I could, either in my own life or other people's.
