nam sicut ille mirum in modum servatus est, cum iam de salute desperaret, ita homines nonnumquam conta spem e maximis periculis eripiuntur.
...actually revisiting this on my quick review of LLPSI Pars I, it seems that 'mirum' must qualify 'modum' and, therefore, must be neuter accusative singular.
I translate it as follows: For just as he was saved in this surprising way, when he had already despaired of life, not a few men have against hope been rescued in this way from the greatest danger'.
