I ам the Good Shepherd - Я Пастырь Добрый
I give My life - отдаю жизнь Мою
No one takes it - никто не отнимает её
I Мyself give it - Я Cам отдаю её
I already have both a dictionary and a Bible. None of this is stuff that I couldn't have figured out myself between the two. If you're going to post random bits of Christianity, could you please at least post random bits of Christianity that are actually useful lexicon and grammar? I don't think you're converting anyone here, you're just reinforcing people's already negative opinions, which I can't imagine is your goal.

And now, I have (shockingly) a few actual on-topic questions. I already know the verb "to pray," but I'm not 100% certain how you make certain constructions with it. For example, how would I say "I'm praying for my sister," in the sense that, say, my sister is ill and I'm praying that she'll get better. Or "I'm praying for world peace," like I'm praying in hopes that it will come about. Instinct suggests to me that one should use the preposition за, but I'm just not sure.

Also, what are the Five Pillars of Islam called in Russian?

I saw a copy of the Koran translated into Russian the other day. I'm kinda kicking myself for not buying it, but it was a little too expensive for me. It would have been an interesting read, though. I wonder if the translators managed to convey the poetry of the original Arabic at all?
