Leading Into Temptation

Et ne nos inducas in tentationem, sed libera nos a malo... Quoniam multa et magnifica supra mandavit hominibus, ut Deum Patrem suum dicant, ut genus suum de caelo cognoscant, ut regnum Dei petant venire, ut non sint solliciti under pascantur, quae omnia magnae spei et justitia signa sunt: ideo nunc additur humilitatis doctrina, ut dum dicunt, Ne nos inducas in tentaionem, cognoscant se esse infirmos, et consideratio infirmitatis causam gloriationis exstinguat. Duo ergo petimus, primum, ut non inducat nos in tentationem: secundo, ut si induxerit, liberet de periculo tentationis. Nam vere, si secundum veritatem justitiae suae examinaret homines Deus nullus posset fieri salvus. Ideo autem difficule tentat, sciens infirmitatem nostram. Aut si tentat, non tamdiu tentat, quamdiu nos vincamus tentationem, sed quamdiu vincere nos velle ostendimus: id est, non virtutem nostram tentat, sed voluntatem: Apostolo nos confirmante, et dicente: Tentatio vos non apprehendat; nisi humana. Fidelis autem Deus, qui non patietur vos tentari supra id quod potestis sustinere. Volens enim glorificare hominem, tentat eum, non ut cum magno judicio glorificet, sed ut ne sine causa glorificet.

And lead us not into temptation, but deliver us from evil... 1 How many great things He has commanded for men: that they name God their own father, that they know their race is from heaven, that they seek the kingdom of God, that they not be anxious how they will be fed, all of which are signs of great hope and righteousness, and therefore He adds the teaching of humility, that while they say, 'Do not lead us into temptation,' they know themselves to be weak and the consideration of this weakness extinguish any cause of boasting. Two things, therefore, we seek, first that He not lead us into temptation, second, that if He does lead, He free us from the peril of the trial. For truly if according to the truth of His justice God examined men, not one would be able to be saved. Therefore with a certain difficulty He tests us being aware of our weakness. Or if He tests, He does so not that while He tests us we conquer the trial, but that during it we show that we wish to conquer it, that is, it is not our strength He tests but our will, which the Apostle confirms, saying, 'Temptation shall not seize you unless it is human. God is faithful, He does not allow us to be tested beyond what we are able to endure.' 2 Indeed wishing to glorify man, He tests him, not that he be glorified with mighty judgement but that not without cause he be glorified.
