uW Translation Notes:

Note 1 topic: figures-of-speech / idiom

ὁ φιλῶν τὴν ψυχὴν αὐτοῦ, ἀπολλύει αὐτήν

the_‹one› loving the life ˱of˲_him /is/_losing it

Here, the one loving his life refers to someone who thinks that his own physical life is more important than anything else. If this clause would be confusing in your language, you could express the meaning explicitly. Alternate translation: “Whoever values his own life more than anything else will still die”

Note 2 topic: figures-of-speech / idiom

ὁ μισῶν τὴν ψυχὴν αὐτοῦ ἐν τῷ κόσμῳ τούτῳ, εἰς ζωὴν αἰώνιον φυλάξει αὐτήν

the_‹one› the_‹one› hating the life ˱of˲_him in ¬the world this to life eternal /will_be/_keeping it

Here, the one hating his life refers to someone who values his own physical life less than he values being a disciple of Jesus. The word “hating” here does not refer to having negative feelings about one’s life or despising oneself. If this would confuse your readers, you could express the meaning plainly. Alternate translation: “whoever values being my disciple more than he values his own life will keep it for eternal life”

Note 3 topic: grammar-connect-logic-result

εἰς ζωὴν αἰώνιον

to life eternal

The phrase eternal life states the result of what precedes it. The one hating his life will keep that life, which will result in eternal life. If it would be helpful in your language, you could express the meaning explicitly. Alternate translation: “and also gain eternal life”
