What to do to have peace in the soul and body? For this you need to love everyone as yourself, and every hour be ready for death.
We cannot see anyone through the lens of our own ego. The ego itself creates such a distortion that our brothers and sisters are transformed from beautiful children of God to a type of monstrosity that exist to do our bidding. And in this place, there is no peace.
Do you want peace? Rip away the very essence of yourself. I want. I need. I deserve. I am. And put on Christ. Not a picture of Christ. Not the thought of Christ. Put on Christ, Himself. And when He has become your Life, you will see that your crucifixion is at hand.
