8969. In temptations a person ought to fight against evils and falsities as if in his own strength; yet he must believe that he does so in the Lord's. If he does not believe this during actual temptation, because at the time it is not clear to him, he must nevertheless believe it afterwards. If after temptation a person does not believe that the Lord alone has fought for him and brought him victory, the temptation he has undergone is merely external. Such temptation does not extend into him deeply or cause anything of faith and charity to take root.
