5.  It seemed to me to be best and least dangerous to take a middle course between desire and fear, and to yield in part to desire, in part to the Spirit:  and that this would be the case, if I neither altogether evaded the office, and so refused the grace, which would be dangerous, nor yet assumed a burden beyond my powers, for it is a heavy one.  The former indeed is suited to the person of another, the latter to another’s power, or rather to undertake both would be madness.  But piety and safety would alike advise me to proportion the office to my power, and as is the case with food, to accept that which is within my power and refuse what is beyond it, for health is gained for the body, and tranquillity for the soul, by such a course of moderation.  Therefore I now consent to share in the cares of my excellent father, like an eaglet, not quite vainly flying close to a mighty and high soaring eagle.  But hereafter I will offer my wing to the Spirit to be borne whither, and as, He wills:  no one shall force or drag me in any direction, contrary to His counsel.  For sweet it is to inherit a father’s toils, and this flock is more familiar than a strange and foreign one; I would even add, more precious in the sight of God, unless the spell of affection deceives me, and the force of habit robs me of perception:  nor is there any more useful or safer course than that willing rulers should rule willing subjects:  since it is our practice not to lead by force, or by compulsion, but by good will.  For this would not hold together even another form of government, since that which is held in by force is wont, when opportunity offers, to strike for freedom:  but freedom of will more than anything else it is, which holds together our—I will not call it rule, but—tutorship.  For the mystery of godliness 1 Tim. iii. 16. belongs to those who are willing, not to those who are overpowered.
