Fight the good fight of faith, lay hold on eternal life, whereunto thou art also called.

No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.

Uphold me according unto Thy word, that I may live: and let me not be ashamed of my hope.
