26 Now power is given against us in two modes: either for punishment when we sin, or for glory when we are proved, as we see was done with respect to Job; as God Himself sets forth, saying, “Behold, all that he has I give unto your hands; but be careful not to touch himself.” And the Lord in His Gospel says, in the time of His passion, “You could have no power against me unless it were given you from above.” But when we ask that we may not come into temptation, we are reminded of our infirmity and weakness in that we thus ask, lest any should insolently vaunt himself, lest any should proudly and arrogantly assume anything to himself, lest any should take to himself the glory either of confession or of suffering as his own, when the Lord Himself, teaching humility, said, Watch and pray, that you enter not into temptation; the spirit indeed is willing, but the flesh is weak; so that while a humble and submissive confession comes first, and all is attributed to God, whatever is sought for suppliantly with fear and honour of God, may be granted by His own loving-kindness.
