Matthew 10:39

Cp. Luke 17:33, where the context is different. He that findeth his life] i.e. saves his life in time of persecution by denying Me, shall lose it in the next world. He that loseth his life, i.e. by martyrdom, for my sake shall find it in the next world, i.e. shall enjoy immortal life. The passage may also be applied to self-denial in general, by which man loses his life of self-centred worldliness, to find it again enlarged and purified.

40-42. These vv. form the conclusion of the charge to the Twelve, and are not to be referred to a later date. In St. Luke the substance of them forms the conclusion of the charge to the Seventy.
