If you want to receive Christ as peace, simply pray the following prayer with a sincere heart:

"Lord Jesus, I do not want to live without peace any longer. I confess that I am unrighteous. Thank You for dying for me that I could be forgiven of my unrighteousness. Lord Jesus, come into my spirit and fill me with Yourself as peace. I receive You as peace. Thank You, Lord Jesus, that You have come into me!"
