ANSWER: Flesh is used in a bad sense for evil inclinations. Hence the Holy Spirit after regeneration resists such evil tendencies which still cling to the newborn soul. This produces an inward conflict, the Spirit trying to keep the man from doing wrong and the flesh striving to hinder those Christian acts to which the Spirit prompts. The Revision eliminates the "cannot" which has no place in the Greek, for God's grace superabounds where sin has abounded.
