Meaning of "yield" in acrostic for 'pray'

Some people expand the word pray as an acronym for: praise, repent, ask, yield.

What does yield mean in this religious context?

Original wording of question was: "Some people expand the word pray to mean..."

Solution 1:

Yield here refers to surrendering to God. This means allowing oneself to be led by the will of God.

Solution 2:

There is no such thing as a letter-by-letter "expansion" of any "word"; this has nothing to do with the English language.

It's just a mnemonic for advertising or memorization, like

  • LS/MFT
