Perfect peace does not mean you are not going through troubles and trials. Oh No far from that. Perfect peace is that type of peace which comes from trusting in God. Knowing that you will come out of it okay. That whatever it is will come to pass. Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day; Nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday. A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee. Only with thine eyes shalt thou behold and see the reward of the wicked – Psalms 91:5-8 KJV. No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the Lord, and their righteousness is of me, saith the Lord – Isaiah 54:17 KJV. He never said the weapon will not be formed but it shall not prosper amen.
