If you live a self-centered life, that is, you always follow your own wishes, I can guarantee that you'll never have peace. Wanting to have everything your way is to shackle yourself to everything. To follow Christ is to live a God-centered life. Now you are free because you no longer need to play God who is now taking care of you. I am telling you because I've gone through all this and know what I am saying. The peace you receive is worth giving up everything in the world for. Basically, it comes down to the truth that God is worth giving up yourself for.
