Be strong and of Good courage
To become strong in Faith one must hear the voice of the Lord of Life and walk as He leads one through all the shadows into the Light of His Day.
Faith allows for the grace to bring our thoughts into captivity, by placing our true enemies (vain imaginations) under our feet.
They may have bruised our heel, yet by grace we crush them under our feet.
All of this is the walk of a true Hebrew following in the footsteps of our Lord.
