All of our prayers for mercy on Rosh Hashanah and Yom Kippur are captured in the phrase:
"Our Father our King, be gracious to us and answer us though we have no merits. Deal charitably and kindly with us and save us."(Avinu Malkenu)
I possess nothing.
I have nothing to give in exchange.
We are not equal.
And this is why I appeal to Your mercy.
–Rabbi Adin Steinsaltz
