In as much as you can trust the Lord enough to lean on him, commiting your hopes confidently in Him and having your thoughts fixed on him; then you can be rest assured to enjoy peace in its perfect state.
Thou wilt keep [him] in perfect peace, [whose] mind [is] stayed [on thee]: because he trusteth in thee. Isa. 26:3
Once your gaze is steadied on looking unto Jesus as the author (source, originator) and finisher (perfecter, completion) of the trust (faith) you have and the peace (rest) you want to enjoy; He keeps renewing for you strength to forge ahead irrespective of all.
