This much must be added: that even those thoughts in which the soul is passive, when Satan casts in evil thoughts which we in no way own, in which he rapes the heart (for if there is no consent to them within us, then it is no more than rape, as it is in the Law)—even those thoughts are often punishments meted out to us because of our neglect toward our thoughts, because we have allowed them to wander
We may feel punishmet of wandering/wayward thoughts that Satan bombards us with when we neglect paying attention to our thoughts. When we do not pay attention to the motions of the Spirit within our thoughts and grieve him by our lack of care.
Taking care of our thoughts matters. It matters greatly and we should be so "in-step" with the Spirit that we are quick to be aware when our thoughts wander, when our thoughts are beign attacked, and when our thoughts are in accordance with the Spirit within us.
