Quenya translation help?

Hi all! Can anyone help me translate the following prayer from English to Quenya?

Eru is my guard and my guide, I fear nothing when I tread in his paths.

(I know it's a Big Deal to name Eru, but this is being said by one of the Numenorean Faithful about to be burned as a sacrifice to Morgoth, so it seems appropriate to me.)

Here's one solution:

Eru kundonya ar tulyamonya, lá rukin aiquallo yá tieryassen telkontan.

Thank you!

I would rather say:

Eru tirmonya'r tulyaronya ná, lá rucin aiqua yá tieryassen patanyë.

Thank you, too!
