How can God "become" something? Isn't He unchanging?

Yes, but we need to use human language to talk about Him.

Also, "He has become my salvation" could just as easily suggest a change in me, don't you think?

Unless, that is, He became salvation by becoming man.

"Has become". Present perfect tense. Are you suggesting that Jesus was born 700 BCE?

It could. But it doesn't.

Who says the prophet was only capable of speaking about himself in the present tense?
